I have just purchased the Garmin GPS 660 and tried to sync-up with my Samsung SCH-A870. I contacted Garmin’s help desk who said if it is not on their Website as an accepted unit then I am out of luck. I was just advised to wait with no idea of knowing if it is on it or not. I didn’t get any feedback from them since. What do I do? Is Samsung SCH-A870 compatible with Garmin GPS 660? How can I get it to work? I would really appreciate your useful assistance regarding this. Thanks.
