Gilly,
I swear the least expensive part is perhaps the most costly, the documentation. Suddenly today the phone worked, the only difference was the car was running and I turned the phone on before putting it into the cradle. The manual says this doesn't matter since it will sync up the next time the key is removed and reinserted.
The other weird thing was the battery was dead last night, not my daily driver, so I charged it up and now have some weird electrical problem with the ABS and Brake assist sensors telling me there is a malfunction. Maybe I had something electrical going on???
