I recently purchased a HTC TyTn II PDA/GPS/Phone. The phone came with a teaser copy of Tom-Tom and I purchased the full version of Tom-Tom VI. As a former user of Garmin City Select for both Palm and Windows Mobile PDAs, I find Tom-Tom to be pretty poor. I'm looking for something better.
So far, I've been unable to find anything, or anyone, that makes quality GPS navigation software for GPS enabled devices like my TyTn II. Pretty much everything seems to come as a package, hardware, software and maps/charts. I have the hardware. I need better software.
