Bit of a pain, I've had an aftermarket HU for a few weeks, installed myself...recently the radio has started cutting out (audio/signal not HU power) when going over bumps, changing gear or engaging the handbrake...
The USB/cd side of things works fine with no cutting out, so i don't think it's a speaker or power issue, more the radio signal being interupted.
Before I go through the faff of removing the HU to check the aerial-in cable connection, is there anywhere else in the car I can check the aerial connections...
Any ideas appreciated :)
