Got the 665 and Bluetooth cell set installed. No problems on the bluetooth, but I made a dumba** mistake on the 665.
Before installing the 665 I plugged the XM antenna directly into the GPS. XM and XM weather worked great! Since I already had a 660 cradle wired into my bike I saw no sense in swapping it out with the 665 cradle since they look exactly alike (MISTAKE #1)! Installed the antenna on the back of cradle, ran the antenna cable into the fairing and put the fairing back on. Took off on a test ride and no XM signal! Did I plug the antenna into the USB port on the cradle harness? Wasn't sure so I pulled the fairing back off and rechecked the connection. It was good. Emailed Garmin and was told the 665 would not work in a 660 cradle. Here's mistake #2. I sold 103Thunder my 660 and of course I send him the 665 cradle! Damn! Anyway, Brian brought the cradle to Ribfest with him and I'll swap it out this weekend. Should fix the problem!
Also, I don't like that big a** antenna mounted on the outside of the bike. Would it work if I mount it under the front fairing? I have been told that it will in the southern states but may have a problem in northern states since the XM satilites circle above the equator. What do you think?
