Is anyone else experiencing or experienced problems with there nav screen or radio display staying on?

I've had the nav screen just stay on when the car is locked next day batt dead then sometimes when I start the car it goes off and doesn't come back on.

Now the nav screen doesn't come on or off but radio screen is staying on when the car is locked.

There is also no sound or options to change it from radio to cd or nothing it's like frozen completely.

The car has been to the dealers 4 times now and they have advised the seems to be a battery drain problem they have replaced the battery and still no luck.

After its 4th visit for the same problem they have told me it needs a hard reset and a software update after completing this eh dropped the car off and it worked fine then an hour later it has happened again.

I'm getting so fed up and it makes it sound as though the dealers just have no idea of what is going on!!!

Isnt there some sort of timed relay to power down - or one of the ECU powers down through a relay?

If it was me and i was having no joy with the dealers - i would have a look at relays to see what circuit keeps it alive when power goes off and pull it.

If you drain a battery, even once, in my experience its never the same - you can probably get away with it 1 maybe 2 times. Mike
