I have just removed the roof aerial on my 03..3.2 and replaced it with a active Hirschamn dab aerial.
My plan is to retian the original ncdc 2013 sat nav but need some advise on replacing sat nav aerial.Previous advise was to pick up the sat nav arial cable in the drivers side foot well and then connect a magnetic type within the roof headlining.
As the original aerial has a joiner at the back roof position and I have got reasonable access with the head lining now dropped would it be possible to just connect into that existing point.The plug on the aerial is a plastic case with 2 black wires and what seems to be a 2 pin plug but all the magnetic type I have seen have the small MMX brass push in.
Is an adaptor available or a sat nav aerial magnetic mounted with the correct type of plug available as I havent any idea how to describe it on a google search
-
From memory, when we met, I thought we had worked out a way to sort all this, but the alzheimer's has kixked in since then. ;D
To try and answer you question, the Roof aerial that you have removed (saloon) has a black plastic twin Coax connector to it, one for GSM, the other for GPS, but I cant at the moment remember what the coax connectors are?
Anything is do able if you can work out what connectors you need and buy an adapter or make up a fly lead for it.
Just remind me what you were planning to do with the now missing Phone aerial?
-
Original aerial removed from roof is in effect now surplus to requirements as I have used the hole it fitted into in the roof to fit my Hirschman dab which has its own lead and 12volt feed running to it.
Sat nav aerial has 2 black wires coming from it about 4 inch long and ending in a plug which was in turn connected to the aerial wire in the roof.
To retain the use of the existing sat nav, although probably will only get used once in a blue moon,I need to source an extra aerial probably mag mounted on the underside of the roof but need to come up with a way of getting the cables to join.In my niavity I had hoped to get a conneter to join the MMX type on the magnetic type to the plug of the cars own aerial if that was possible

Yep, the black plastic connector, actually has 2 x Coax Connectors in there moulded as a whole connector, think thats why I suggested you use the foot well connector as there split into 2 down there. suppose you could source the the other end on the Aerial plug under the roof lining and adapt that with the right connector to suit your GPS mag mount idea, but the aerial wouldn't work under the Roof Lining, it would need to sit outside or be parked on the front dash or rear shelf so it can view through the glass upwards, another reason it would be easier to use the footwell connectors, if all that makes sense.
-
Ok...will leave the loose plug in the roof lining and put it all back together.
If its easier to pick up at the foot well thats where I will next look and see what connections are down there.
Hadnt realised all aerials require an " external sight of view" so maybe a glass mounted aerial would be the way to go ?just need to find a way of linking up the cables.
So the loose 2 wire plug in the roof is for both GSM and GPS...1 lead for each ?

Yep, shame (I guessing not long enough) that lead cannot be pulled back and routed to the back parcel shelf and fit the old aerail there to get you out of trouble for the time being. ;)
-
I will see if I can pull the old lead out of the roof from the drivers side rear wing panel that way there will be atleast some lead visible.
Might then be able to get a glass mounted aerial for the rear screen...just need to work out how to join them all up as I imagine all glass type aerials will only have a single lead connecter and I need to first work out which of the 2 black wires is for the sat nav,then get a plug to join up.
Dont supose I could cut the plug off the old removed VX aerial and some how join wires to a plug that would connected to glass mount.

Cheers for picture Rob. :y
Looks a whole lot easier picking up those connecters,just need to source a suitable fly lead to go from the sat nav connecter to plug type on a screen mount aerial as don,t fancy anything magnetic stuck on the outside of the car
-
I'd pick up at any convenient point near the back, and put a mag receiver above the metal but under the composite part of parcel shelf. Works well, as no metal shielding it

That's where I put the Tom Tom external aerial for my ancient Go model. :y
Works well when I have to use the hateful thing which isn't often thanks to having the NCDC working now :y
-
Good idea about the location of the mag mount as can get it under parcel shelf as most of the back is stripped out.
Had a closer look at the original VX aerial and quite simple to pull apart once the silicone is removed from the 3 screws and back cover removed.
Now have 2 black aerial cables and the shaped metal base plate...1 is soldered into a white dish washer size tablet with 7-253 stamped onto it and has a metal plate which seems to earth onto the base plate..other wire is soldered into a circuit board which then has a peg which when refitted connects to the base of the stubby rubber aerial.
Question is which one is for the GPS and which is for the GSM as if they can be identified it would seem a simple soldering job to get a plug which can hook up to a female MCX plug.
Getting there
-
Use a meter from passenger kick panel to positively identify. Been a while, but vaguely recall at aeerial, they all look the same
-
Yes both leads look identical at the aerial joint..just wondered wht the white tablet thing was .maybe its an amp for the gps.
Will get meter out and see which is which
-
If its pluged into the HU then the GPS one will have +volts on the centre core pin, where as the GSM one wont. If the cable reaches to the back parcel shelf then just unscrew the GSM whip from the old aerial base and stick that under the rear parcel shelf, the right way up. :y
-
No need to earth it to the metal body work then ? as original base is bolted down through roof skin and hefty metal nut forms eath.
Aerial base is in bits at the moment but can put back together and will see where i get pulling aerial cables through maybe tomorrow afternoon then
Thanks for advise guys..much appreciated :y
-
Just to add, the GPS aerial will not function with anything metallic over the top of it, and requires fitting in a flat location that gives it a clear unobscured view of the sky. That said, if that position can be achieved by placing under a fabric rear shelf, or thin plastics under the top of the dash, then that is fine also. No need to have it visable as such
:y
-
Thanks guys. :y
Have decided to go down the magnetic mount route and fit it central on the rear parcel shelf under the fabric cover which I hope will provide a good view to the sky and be totally out of sight.
Only slight problem I am now finding is how to connect the MCX male connecter on the mag-mount satnav cable into either the existing roof plug.(which i dont think is an option) or into the plug connection in the drivers footwell which RobG kindly provided me with a great picture of.
Anybody know if such a female/male fly lead is available to link this up ?
-
When I bought a DAB aerial from Panorama-Antennas (http://www.panorama-antennas.com/index.php?route=product/product&product_id=95) I had to specify the connection I wanted on the radio end of the lead from the roof mounted aerial because they make they leads to order.
I guess that answers the question..........
PS they probably make a multifunction roof mount aerial that will save you pulling the parcel shelf out.
-
Cheers for link Andy. :y
In truth I actually have a dab aerial and have removed the exiting GM roof areial completly and replaced with this into the exiting roof hole and all is fine on that score. ;)
What I need is a connection or flylead that allows me to connect into the existing GM sat nav cable in the drivers footwell from that to a MCX plug on a mini magmount which is now under the rear parcel shelf...trouble is I dont know what plug GM have used or what it is called to decribe to a supplier or even a google search.
Need the type of plug description :y

Might be worth whipping the Foot Well panel off and have a look or take a Pic and see whats down there, if this is for your MPF then it should be as per Robs Pic.
Seem to remember you were talking about a newer 3.2 FL at some point, if its for the later then fairly sure they may be different, later ones had a all in one Blue or Grey Connector for the Comms down there.
-

When I placed my order I did it by phone because I wasn't sure exactly which plug I had. The guy at the other end was both patient and helpful and was able to identify the plug with the barely adequate description I gave. I imagine that a phone call (followed by a photo if necessary) would have you sorted. :y

Correct.
-
I think the micro connector is a 'Fakra' one IIRC
-
I will give them a call on Monday as I only require a fly lead to connect MCX male to what ever lurks in the drivers footwell.
Hi Zirk...yes car is a late 2003 3.2 Elite so imagine its one of the last ones "out the pot" ;D
-
This sat nav aerial lead is starting to do my head in >:(
As advised I have removed the kick trim in the drivers footwell expecting to find the connections as per RobG pictures.
Wrong >:( what I have is a Blue plastic cable joiner block..into this runs 2 black leads which appear to be the same as those at the roof areial so expect 1 is GPS and other GSM although identical cables with no plugs.Coming out of the other end of this same Blue junction box is just 1 black cable with a thin red/black wire and they go up into the dash area.
The radio aerial which I assume is the grey wire also goes into this junction box and the same grey wire conmes out the other side.
So in effect they were joined but in the factory and there is no visible means of removing them.
I am now faced with several options:
1)..just give up retaining the original GPS the car was built with as I will have no suitable aerial
2)..remove the headunit and get a suitable connection from there into some form of internal mag mount GPS aerial
3)..cut which ever wire is the GPS aerial feed into the headunit at some point near the rear of the car and try and get a plug onto the wire allowing for it to connect into a mag mount GPS aerial on the rear metal parcel shelf.
Any advise on options 2 and 3 ::)...before I resort to option 1 :(

Yep, later type, dont give up on it now, your almost there. So in effect you have 2 x male and females at one end and the same at the other end, so in theory should be able make up a lead to suit your needs somehow.
Are you passing me at any time in the near future Andrew?

Hi Chris .
Car is still very much a "work in progress" and am slowly getting bits done as and when I have the time as only really want to start driving it when all is done that way it will start earning its keep.
Blue connecter in drivers footwell has no means of removing any of the cables so it appears it was some sort of joiner but put in during manufacture.
I currently have 2 black aerial wires at the point of the original roof aerial hole which are in 1 solid black plug type connecter.Unsure which is for GPS and GSM as they have no identification and the plug is the reverse of that which joins into the original aerial flylead.Had hoped I could get something to join into that but only peice I have is the bit from the aerial base which I assume could be butchered into a suitable connecter.
Dosent look too promising at the drivers kick panel area as no means of getting into that,again only by cutting bits open which might not be the right cable.Logic seemed to point to removing the Head unit and seeing what typ of plug that took ,then getting a small flylead made to plug into the Headunit and a male MCX type connection then I would be sorted.
Suppose the 2 questions are:
1).. what type of plug is required to go into the GPS part at the back of a NCDC2013.
2)..Can you get a female joining plug or flylead for connecting to a MCX male plug
-
Best advice I can give is not to intercept the connections at the HU unless you really have too. The cable and plugs can be removed from the blue outer by depressing the little tab with a small tool (A dart will do!).
-
Well I think I may have come up with a plan but just need to confirm with you guys. :y
I have cut the 2 cables from the original roof aerial fitting as it was surplus to my needs.I now have the original black plastic plug which will connect into the aerial lead of the car so in effect have 2 bare aerial wire ends,1 must be GPS the other GSM.
Searching internet it seems you can buy a female mcx plug so can I just fit that onto the exposed aerial cable of the lead that is the GPS one and then just plug in any mcx male lead from mag mount ?..Can it be this simple really ;)

Could be, but the female plug you can buy will almost certainly be a Crimp type, so you will need the crimp tool.
In fact thats all I was going to do, if you came over this way, lob both the the ends off and crimp a couple of thin 50 ohm in line connectors in there for you. ;)
Suppose you could find a local AV guy locally that knows what there doing and ask them.

Sounds like my plan is a go-er then. :)
PM incoming Chris :y
