There are huge ones that are cheaper but the smallest is the Holux GPSlim 240, which doesn't cost a whole lot more than the others, (maybe $10-20 more at most)
Cool, about how much does that go for??? (USD) and whats a good program to use in conjunction with it for mood well detailed, up to date maps. Mind you I have an E70-2. Any other opinions???
I'd suggest either of the Nokia ones for the sole reason of compatibility. You can use the same charger in the car for both your phone and your bluetooth gps. Just one less cord cluttering up your car. I have the LD-1W and it works great with my N73.
aside from the same batteries and same powercords the holex should be comparable to the nokia one, perhaps even better since it has the newer gps chipset compared to the nokia one (from what i know of the nokia ones)
