My satnav in the omega seems to think northern ireland is in scotland. im using a 2008 Navteq disc for UK and Ireland on a CD-R...would the CD-R be causing the issue? i know the NCDC dont like CD-R's but im testing just, its been working fine for a few weeks now and its only just started this problem when i got the CID fitted at the weekend (which still needs the trip computer reprogrammed, help there would be good...ie the codes for my particular car and/or where in TechII you can change it!)

I can buy the genuine disc for £67.10 delivered from the Navteq site but before i do id like to work out whats going on!

The sat nav antenna is a seperate connector to the radio antenna and can easily be broken, is the unit sitting fully home in the cage?

miniator · « **Reply #2 on:** 08 June 2009, 19:14:00 »

yup pretty much, the HU hasnt been removed since easter though

Dave DND · « **Reply #3 on:** 08 June 2009, 19:15:36 »

Sounds like a broken connection or faulty GPS antenna

miniator · « **Reply #4 on:** 08 June 2009, 19:21:10 »

can they just break? it was working at the start of last week!

Check HERE for navi disk i offered him £27 and he accepted

If not seated properly (and it didn`t break when fitting it) then it can often fracture under vibrations (ie driving) The connector is very fragile and easily broken, but the symptoms you describe are absolutely classic of no GPS reception and it is simply driving around using the speed pulse and the gyro.

You should be getting some form of error message if the GPS receiver isn`t working - Somebody will be along shortly to explain what and where you can find that message. The other option is to beg, borrow or steal another GPS aerial, plug it in and see if teh problem resolves before spending out on a new one, although that said, they aren`t expensive - often found on the German ebay sites for a fraction of what they cost here.

miniator · « **Reply #9 on:** 08 June 2009, 22:57:37 »

ive no error msgs at present, just that the route cannot be calculated.
Do i need the whole aerial or can i just track down a connector?

back to german ebay, thats where the CID came from!

Can you reprogram in your current location at all?

Can you access the test mode, or screen to show signal strength / sattellites received?

Others may be better at guiding you from here (excuse the pun)

if the gps airel breaks down no error codes will come up

go into the main settings on the internal settings i think it is and you can check the status of the airel there

Different system Nick, this is the Siemens unit not the Phillips Carin.

Either would do -

An error code showing a fault would be good, and some form of signal strength or sats received showing NO SATS would also indicate the failure of the antenna

Dave, can't program my location at all and the only data i can get from the CID is the longtitude/latitude location, and the nearest town/area....which is currently newton stewart!

Would this need to be TechII'd to get the error code you think?

Dave DND · « **Reply #16 on:** 09 June 2009, 12:07:35 »

tech2 is never a bad idea for checking out errors, however, a new GPS antenna is usually cheaper than a tech2 session.

I know which I`d try first, as the antenna can always be sold on afterwards if it proves to be something else.

miniator · « **Reply #17 on:** 09 June 2009, 12:14:47 »

just to clairfy dave, when you say antenna....

do you mean the roof aerial or the connector for the HU?

i can get a TechII session for free (or very little) too

Dave DND · « **Reply #18 on:** 09 June 2009, 12:52:42 »

The GPS aerial

Others more familiar with the Omega can advise where its fitted.

miniator · « **Reply #19 on:** 09 June 2009, 13:01:26 »

from what your saying its under the dash somewhere??

VXL V6 · « **Reply #20 on:** 09 June 2009, 13:04:13 »

Right, firstly, in the top right hand corner of the CID screen is the GPS logo red, yellow or green?

GPS antenna is on the roof (base part of the cellphone antenna) blue connector accesable under high level brake light roof panel but it's unlikely to be there, another connector in drivers kick panel, again unlikely to be a problem there. Most likely connection fault will be the right angled plug on the head unit cage.

miniator · « **Reply #21 on:** 09 June 2009, 14:03:42 »

the GPS logo is red....so im guessing thats bad!

unfortunately the car is the bodyshop at the mo, but when its ready ill have to take a close look at the back of the HU (saturday evening). I had the HU out to change the trims so i guess your right VXL!
Ill have a look at all the connections, starting with the aerial, just to be sure. When i know more, ill update this thread.

If the HU one is found to be faulty, is the only option to replace it?

VXL V6 · « **Reply #22 on:** 09 June 2009, 14:30:27 »

It may have just pushed the right angled connector off the back of the cage (head unit plug itself is pretty solid).

If you remove the head unit (watch the bezel!!!) there is a single screw holding the cage in place, the cage can then be slid out by pressing the top and bottom of the cage together and sliding.

miniator · « **Reply #23 on:** 09 June 2009, 14:47:03 »

ah right ok, i didnt know that. Cheers man for your help, much appreciated! hopefully i get to the bottom of it simply!
ill update my findings at the weekend all being well!

miniator · « **Reply #24 on:** 14 June 2009, 00:22:05 »

ok, had a nosey tonight there and it would appear that the GPS lead has become loose in the back of the cage.

tried to get the cage out but didnt have the time to do it properly. however, it does seem VERY secure....other than the screw in the back and the clips around the edges are there any other hidden screws/clips???

TheBoy · « **Reply #25 on:** 14 June 2009, 09:06:51 »

As VXL said - GPS wording in top right:

Red - no sat fix
Amber - 2d fix only
Green - Sat fix

With these units, its common for the cage to slightly distort, causing a poor connection on the sat connector.

Cage is simply held in place by the 2 tabs either side, some have a small bolt at the back right in the centre.

miniator · « **Reply #26 on:** 14 June 2009, 10:57:15 »

small update.....

got the cage out and removed the connections from it. plugged them all into the back of the HU and now the satnav has positioned the car in my backyard. It even calculated a route on the map display, still only an arrow on the other display. When i drive the car the arrow moves in a random direction, not following the road. GPS is still in red!

new aerial lead needed?

Is it seeing any satellites?

For info, I am yet to find anyone who can provide the plug that clips into cage (and believe me, I've tried).

There is a seller on egay who sells suitable satnav antennas for these (as well as the carin type), around £5 + £2 p&p. These would mean modifying the cage so only the very front of the cage is used (simply to hold stereo in place), and then plugging the leads directly in back. Not ideal.

miniator · « **Reply #28 on:** 14 June 2009, 13:05:29 »

I can only assume that it still isn't tracking any satellites as the GPS in the corner is still red!

Do you have a link for the ebay aerial? I think its worth a try to at least work out what's wrong!

Press and hold MAIN for about 8s, then press NAV, should get a shit load of diag info. From memory, first number is number of tracked satellites.

i should also say that your hold MAIN then NAV didnt bring that up...and the best thing is i cant say how i did get it!

anyhooooo, i think i need to try a new aerial? you dont happen to know what connection type i need to search for? cheers for all your help btw

Dave DND · « **Reply #33 on:** 14 June 2009, 18:16:08 »

I`m puzzled a bit -

You must have received something for it to relocate your position? Yet screen shows no reception. Certainly seems like an intermittant GPS antenna or dodgy connector to me - the fact that it did relocate and calculate a route, would indicate to me that the main unit is probably OK. Random direction is to be expected with antenna failure, and will just keep travelling where it wants to.

I have a spare from my spare ncdr1100, but by time posted to you, then you back again, probably as well to buy your own.

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260265025329

That is the company I used, and connector type is SMB-M

For those needing CARiN ones, same seller, similar item but SMB-F

Note it is not a right angled connector, so cannot be used with full cage

Not sure that would fit the plastic clip that holds it to back of cage - if it would, that would be better bet if available in SMB-M

got my ebay aerial today, plugged it in and hey presto it worked straight away! ive the aerial run out to the scuttle panel for now, but its not ideal!

gonna get a second aerial from a broken saloon and replace the the seperate leads (HU to kick panel, kick panel to roof, and the aerial itself) to see what part has actually gone!

thank you very much for all your help folks!

Don`t shield it from the satellites by placing it under the metal of the roof!

You can put it under plastic and fabric, but not under metal.

Under dash or rear shelf are often favourites - gives it a good unrestricted view upwards

tried under the dash too, just in with the head unit but couldnt get a signal again.....will try it again although ill lift it up higher in the dash to behind the CID!

some areas of dash have metal formers in them, avoid these areas, and not uncommon to wait 20 mins to lock on to a set of satellites if starting from a very "lost" position.

From an 'unknown' location, expect 5-20m for a decent fix. Once fix established, should be fairly quick (assuming you don't remove power to HU)

tis now located under the dash, behind the CID and working a treat!
