Question about 2003 BMW 330
The car is a 2002 bmw 330 ci conv. The indash navigation, tv, radio, cd, and screen not working. All controls on head unit are dead and the screen is blank. The hand controls on the steering wheel work the radio and the blue tooth. All fuses are good in trunk and in glove compartment. BMW dealer wants $4,000.00 to replace both front head unit and trunk unit. It can't be both. How do I tell whats wrong? Any good ideas?

Thats an interesting one. My first suggestion would be to look at the DVD navigation unit in the trunk, does it have any sign of life, i.e will it eject the map dvd is there a blinking redlight etc, if there is nothing then thats most likely your problem if there life in it then I would suggest having a closer look at all the connections in the trunk. You need to remove the side cover in the trunk and check the connections.
If the above doesn't help, my guess would be your head unit has the fault.
The cheapest way to get this repaired is by process of elimination. If you think the DVD unit in the trunk is faulty I would buy one from ebay if you find this doesn't solve your problem you can always resell it on ebay without losing money and the same with your head unit.
Hope this helps. Good Luck.
