Bob & Brian - this is an aftermarket install that I performed with the kit from EAS about 4 years ago.

I'll try putting my phone in the rear compartment and see how it performs as well as checking out the connections.

How would I find out if there's a better antenna available?

Also, I recall when installing the dock in the oddments tray that there was, what appeared to be, a BT antenna in there. Is the one in the trunk the only antenna in the X5?

Thanks!
