Do you use a cell phone with data plans? If so, a lot of the phones have navigation for free.. Google navigation works pretty well on most phones…
I’d save yourself some money because there is quickly becoming a convergence in handheld GPS for driving and cell phones….The cellphones are getting much more powerful and pretty soon there won’t be a need for a GPS only device.
That’s why those GPS companies all the sudden are trying to get into the cell phone business….Because they know their days are numbered.
FWIW, phones pretty speedy that can do this reasonably well.
1)HTC Incredible (Verizon)
2)HTC EVO 4G (Sprint)
3)HTC/Google Nexus One (aka Passion)
4)Samsung Galaxy series…
5)I use to recommend the Motorola Droid. But it’s outdated already and most likely won’t be able to run the next next generation o/s (gingerbread)…
Disclaimer: I’m biased, because my touches a lot of these google phones.
