I have the Nav II GPS and love it. However the screen's protective cover cracked and peeled away. That and the fact that one has to selectively load maps to the memory card makes me want to upgrade to the Nav III.
When I last inquired months ago my local Denver dealer said the current version was actually the Nav III+ and that he wasn't sure what the + did over the standard III. He also suggested that surely the next version, Nav IV?, must be due out soon.
Anyone have any info on the III vs. the III+?
How about rumors of an even newer unit.
It's off season sales time here in the Rockies. I'd love to take advantage of current discounts and upgrade my GPS before crusing season hits.
