My highline wants to play
 

As above when im going along the road my highline is 9 times out of 10 absolutely fine.
The other 1 time i change the radio station or put the cd on and its stuck on the previous screen and stays like that for about 5 minutes.
Ive also had it where it wont let me do anything like ive been locked out.any advice would be greatly appreciated thanks Thomas

Have you checked for water in the wheel well?

Thanks its all bone dry.
Thanks again Thomas

Try unplugging the boot units, spraying the connectors with electrical cleaner and plugging / unplugging a few times.

Thanks sir i will give that a go

My sat nav worked ok for a couple of days- for about 20 minutes showed up the green dots for satellites but yesterday had a hissy and now is driving round an industrial etsate about 5 miles away:D

Ive just spent nigh on £22 on some knobs so im going to beat this and get it working if it kills me:D

R.I.P. Thomas.
