I bought a used 2006 X5 with 42K miles. It has nav and bluetooth. I have Verizon Storm Blackberry. I was able to successfully sync and use for about a month. Then all the sudden it just stopped working.

I took it to dealership. They charged me $124 for diagnose and said that the problem was caused by me using a phone that was NOT compatible with my X5's bluetooth and therefore it is not covered by warranty. To fix it would cost about $900 for new part and labor to re-program.

Am I really just out of luck here?
