Got a 2005 Mk3 GS300 a couple of days ago - really enjoying it so far, but I've noticed that the iPhone charger that I've used in my previous car without issue interferes with FM reception to the point that only one or two stations can be received.
I could live with this, if Classic FM (which is where the TMC info is pulled from) didn't get nixed too.
It's a Belkin USB adapter, which is an Apple approved charger. Even interferes without the phone connected, but as soon as I remove it from the accessory socket in the console box, FM reception goes back to normal.
Is this a known issue with this particular car, or is it likely I've just got an incompatible charger?
