After much trial and error I finally was able to install the Garmin Mobile XT software successfully to my Axim X51V. It is very important when loading to an SD card that you either install the software using the Garmin setup files or through active sync on a ppc.
If all is done correctly you will not see the 4 option screen when you activate the software. It will go directly to the safety message screen for you to agree or disagree.
The install directions that accompany the download are excellent, be sure to follow them.
