So I've read quite a bit about the xc90 audio system, the fibre optic loop, roof mounted aerial, Volvo security system etc etc...
Problem I have is that when on radio, FM and AM only I get a clicking noise through the speakers and every now and then I loose rear speakers, on CD everything is fine thus why I won't be spending £££££ fixing this so question is really to see if anyone has ever had this problem? I've seen other audio system faults ie total failure, display going etc but not my one? I haven't got VIDA yet so can't check with that and question one is will it see a problem with audio/check audio system etc etc? If someone has one local to me (Essex) and can plug it in and check happy to pay some beer tokens.
I personally think it the "radio" part of the system, some component on that board? I've had it all part today and resoldered a few bits in case of dry joints,One thing I have noticed is that it "clicks" with engine on or off, all other electrics off that can be. If I put a power probe into the wires into the the unit you do notice a "flicker" on 4 of the wires, 2xwhite and the 2x green. There are 2 outer wires which I think are the power to unit? ANYONE GOT A WIRING DIAGRAM FOR THE AUDIO SYSTEM SO I KNOW WHAT/WHERE THE WIRES GO?!
I haven't tried a mini disc as haven't got any to try, something I'm thinking of having a go at is to "convert" the minidisc to a aux output so I can plug in iPhone etc and simply select minidisc but the output will be from the iPhone/iPod, I've seen people do a aux out of the aerial in boot but I'll technically have the same click through the radio channel!
Re the security systems on the Volvo, anyone know for sure what is coded? if one was to replace the cd unit, minidisc unit etc would they all need coding or whatever Volvo do or is it one specific part? Point I'm getting to here is if I were to buy a new "radio" part which BTW I think is called the ICM? Would that just plug in and work? Hope that all makes sense to some helpful xc90 specialist!!

On a sub note has anyone on here ever "by themselves" got rid of the fibre optic system and fitted a standard style stereo system? I can see this would be a right ball ache as it incorpates everything! Coming from someone who is quite at home fiddling/fitting stereo systems over the years it's a minefield the xc90 system, even not having a standard aerial lead threw me!
Please don't shoot me down with the why would you want to and take it to the MD etc, it's a cheap XC that I'm doing myself and as said at the top I can live with the radio like it but it would be nice to fix if it's easy one like a handful of things I've done so far with advice off here like the mr muscle VNT clean.... Love it!
