I've trimmed out what I think to be unnecessary from the diagram and specifically for what I want to do which is get rid of the gps puck and still have everything work as it should as if it came from the factory. Does anyone see any problems in the wiring diagram that I'm missing?
Parts are as follows...
1 – Aerial -R11-
Roof aerial for navigation, telephone and auxiliary heater telestart
Installed on rear of roof
2 – Aerial connection for auxiliary heater telestart
3 – Connection for mobile telephone -R54-
4 – Aerial selection control unit -J515-
Only installed in conjunction with control unit with display for radio and navigation -J503-“RNS MFD 2” with CD player.
5 – Aerial amplifier -R24-
For FM reception
6 – Aerial amplifier 2 -R111-
For FM and AM reception
7 – Rear window with two aerial connections
For FM and AM radio reception
8 – Frequency modulation (FM) frequency filter in positive wire -R179-
Installed in wiring harness
Has the task of preventing the aerial signals being shorted to earth
9 – Amplitude modulation (AM) frequency filter -R177-
Installed in rear lid
Has the task of preventing the aerial signals being shorted to earth
17 – Heated rear window voltage supply, negative
18 – Heated rear window voltage supply, positive
19 – Frequency modulation (FM) frequency filter in negative wire -R178-
Installed in wiring harness
Has the task of preventing the aerial signals being shorted to earth
I think I only need part no 1, 6 and 8 to get everything to work? Part 4 can be discarded as my head unit is the RNS 510 and parts 17,18 and 19 are already in place with the rear heated window. Part no 6 is on ebay and think it might come with no 8 already wired in. The tricky bit is theres nothing in the existing wiring loom I can see to connect the new parts too??
Ideas and suggestions please. And if this seems like a pain in the arse of a job to do, it's only because I've got the headliner out due to a leak from the sunroof and thought while its out what else can I change or update.
And yes stripping out the headliner is a major ball ache
