Thanks Zirk - very comprehensive. Amazing there are so many permutations.
So I think the car is a type 3.
My guess also if your have sat and phone in the Estate (NCDC2015 with Nokia Telematics in the glove box?)
My old saloon (mfl) has a completely different stubby aerial which I always thought was GSM (or GPS?) only, FM being in the rear window. Are the fl saloons different? Visually the breaker base looks similar to the one on the car, apart from the cables.
Correct, stubby aerial is GSM (1/4wave whip roughly 3 inchs) GPS will be in the Base (Oval type not the standard base) and correct again FM via the rear screen.
FL Saloons the same, although no idea whether same part number, believe connectors may be different (or at least the plastic housing).
I don't have a whip at all -either with the car or the breaker base. Is that going to be a mare to source? I see loads of aftermarket whips on ebay - I am assuming they are FM. Need to have another look.
The whip for the Estate is FM (FM and GSM on number 3, but we will forget about that for the moment) The whip is about a foot long (1/4 wave wire wrapped around a fibre glass rod) there all similar on the VX range but may have different thread size (as said the FM / GSM os different again on the MIgs).
I don't quite follow:
you will have to pin out the centre pin (buzz it) to the outer threaded part of the whip.
what do you mean by the centre pin? and apart from continuity what am I looking for?
Continuity test, yes (ie buzz it), the cable outer (screen) is a common ground (all cable are earthed to the metal Base) so that wont tell you much, so you will have to buzz the centre pin to find out which one goes to the threaded whip, the other cable will be GPS which goes to the GPS input cct pcb inside the Base, If your carefull and know what your doing, you can take the base apart and physically see which one goes where if your careful. warning there's a screw inside the threaded whip part that needs to be removed or your break the connection to GSM or FM.
Then you just need to work out what base you have, Saloon or Estate, as said the Saloon will have 2 x 50 ohm cables with 50 Ohm connectors, some were screw type (FME from memory) and some are Farka push fit (again different). on the Estate same deal except the FM will be 75 ohm cable and different 75 ohm connector, slight clue hear the FM 75 ohm cable should slightly thicker (not much) than the 50 ohm one.
