I have a Dell Axim X3i and a Garmin GPS V. I was wondering if I got the correct cable to hook them up, what would the Axim be able to display for me that the GPS is not already doing other than maybe a color picture. What do others of you use this type of setup for? I only see a use for the storing capability of the maps on my 512 SD card on my Axim. Any info on this matter would be greatly appreciated.
