I have a bluetooth Garmin GPS 10 (precurser to the Mobile 10) and use it with Garmin XT software on my i760. The software and City Navigator 7 maps are all loaded on my own SD card since long before Garmin started pushing everything on their own card and it works well.

I would like to upgrade to the NT maps (2010), in particular to use the traffic feature, but I do not want to lock myself into one of Garmin's proprietary SD cards. Does anyone here know if this is possible and what the specific part number would be for the maps, which I presume would be on a DVD that I could then load on to my SD card. I have recieved conflicting information from Garmins' technical support.

Thanks,
Steve.
