I was wondering if anyone has had success using a Bluetooth GPS with their iPod touch. I happen to have a Bluetooth GPS (i-Blue 737) which works with my Blackberry and with my Macbook fine. I (with very special permission -- she doesn't usually let me touch it) borrowed my wife's iPod Touch. However, it couldn't seem to find it at all. Her iPod Touch is a second generation with the 3.1 software installed. My Garmin GPS is on its last legs and I thought that when it finally died, rather than replacing it, I might get a touch. However, if it can't act as a GPS, that won't be possible. Was I doing something wrong, or does the newest iPod touches work with these types of Bluetooth devices?
