2003 X5 4.4 no nav bluetooth problems

[utdeveloper]

Ok, so here is the story. I had the bluetooth installed at the factory dealership here in Houston and it absolutely sucks. I have had bluetooth in the past, 2005 525i, and all I can say is that I am VERY disappointed. Is there anyway that I can have them uninstall the bluetooth system? It is unusable to the point where I have had clients tell me to call them back because how bad it is, which in turn hurts my business. I am in real estate and spend a lot of time in the car so I really wanted this system...but for $799 it isn't worth it.

So, what are my chances of being refunded?
