Which type card does it use Jeff...SD?
They may be an MMC type (is that right?) but they appear they may be proprietory...not sure on that since I just bought one off of ebay.
I just downloaded data to mine tonight. I found I have a 256 and the 128 supplied with the auto kit.
The 256 took all Maps from Vancouver BC through half of Montana down to Western New Mexico and still had about 40mb left of the 256. That included all cities (like Seattle and LA). I then loaded everything to the right, and got the rest of Montana, Utah, Colorado and New Mexico plus parts of Kansas, Nebraska and Iowa into the 128 card. I bet a 1 gb (not sure if it supports that large of memory or not) would get most of the US on it. But boy it will take a couple hours to complete the download.
