I just purchased an 05 X3 3.0 in mint condition. It runs and looks great.

The keyless entry works everywhere I go except where I work, so far. There is a large radio tower across the road from the parking lot. Could that tower prevent the keyless entry from working? Coworkers do not have the same problem with their cars (not BMW's).

Does anyone know how many speakers come with the standard audio system? I found one in each door and one under each of the front seats. What are the speaker sizes? The amp in the truck, is it a two channel or four channel amp?

Thanks for any help you can provide.
