Rating : - Why don't they have a no star rating?
I bought an Axim x51v hoping to use my Street Atlas Handheld software on it but after just a few minutes of use I started looking elsewhere. I concur with all the bad reviews it has gotten simply because of the hassle you are put through assembling and transferring maps to the handheld unit.
I have not been able to transfer routes from my laptop to the PPC. That would be easier than trying to do it on the tiny screen with a stylus and all the controls that better software has is totally missing on SA Handheld.
My advice is "Don't waste yor money on SA Handheld".
