Not very good at navigating this site so I'll re-post my problem. I have an RX450h, 09 plate, in very good condition apart from poor radio reception which could be part of a bigger electrical problem.

I don't have DAB, definitely, and all the stations on AM frequency suffer from distortion. FM, oddly, seems to be fine.

More worryingly, the main control panel (don't know what you call it) which accesses the nav, audio, ventilation controls, etc. has twice completely died. Dead screen apart from a frozen nav. After half an hour or so it comes back but something clearly is dodgy. Any ideas?
