I am the exact same problem with my new 2013 Jeep Overland Uconnect 730n (RHR).
"Navigation Data Base Not Found" at start-up.
POI Data missing.
"Take Me Home" address lost.
Address Book data lost.
Cannot stream iPhone via Bluetooth,but can play via Aux cable.
Cannot initiate outgoing phone calls hands free but can using phone or manual screen input, incoming calls can be received.
Did you find any solution to the issue? Uconnect tell me that it is because I am in a different region as to where I purchased the vehicle. Bought the vehicle in Texas and currently in Mexico.
