So ... I've tried both Magnolia and Skyraider, and love them both ... BUT ... On both of those, my GPS seems to be gone. I can go outside, on a clear day, and ask for nav directions somewhere and it just hangs on "Waiting for GPS". Navigation is a key feature for me, so I can't give it up ... did I miss something in the installation? Do I need to install something additionally? I simply backed up, wiped back to factory, installed ... Any help would be greatly appreciated.
