iQue 3600 and VISTA

I will never have another iQue 3600 - Once I was able to get everything to work, I wanted to place a new map on the system. Just try to delete the old and place on a new. It keeps telling me that I have a map on the SD card. There is no map at all now. This iQue will not work well at all with VISTA.

When the battery goes dead, you got it, re-install from scratch. Totally frustrated. Support is NO HELP at all other than tells me I have a problem.
Anyone has a solution to the hundreds I've tried email me at delravenus@yahoo.com

VISTA and Garmin make me think twice about buying another device.
