It started every once in a while and now the navigation system is simply not working. There is an ERROR MESSAGE on screen all the time. I took it to the dealer and they said the DVD is fine, the problem is the reader. It will cost me more than US$ 800. Does anyone knows how can I make sure they are not misleading me?
Thank you!

Hello
The engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
