Palm® GPS Navigator

[plaino]

I am looking to get gps for my treo 700wx. I saw palm has thier own gps through tomtom. everything looks nice but there is some weirdness. They have two editions, edition 2 and 3. I look at the description and they are almost identical except for a slightly updated software package and the cradle being slightly more form-factored for the treo in the edition 3. the price is only a $21 difference.

am i missing something? is there anymore of a difference between the two. i dont see a reason for releasing a edition 3 if they are so similar.

anyone have any input on these if you own/have used them before or thought about it? any ideas on if there is something better?
