using Iguidance here on PC and PPC.
I've tried:
- on course navigator 5 (slow as @#$% on my
Axim x50v, and on my
HTC SX66 blue angel)
-Teletype (missing many streets)
-Deloreme (missing info on one way's)
-Destinator (dont remember what went wrong - oh yeah, to many steps to get anything done.)
None had a trial.
GRR!! ... so did download them via
bit-torrent to try them.
I ended up purchasing I-guidance because they were offering registered users an update

Seems they care unlike the other software mentioned which has not offered any updates to a few known issues.
