I have an iPhone 4g, but I've never used the bluetooth feature for navigation. Can you explain how you navigate with it. Also, I'd love to see how you mounted the charger, etc. Maybe all of this is in another thread, but I didn't see it. Thanks!
1. I use a GPS application called Sygic
(Map My India), its pretty good! It is also available for North America and Europe.
Well for USA you have tons of GPS apps...but for us stuck here, there are only two options
Sygic and Navigon (Navigon is crap)
2. I have tried to setup a charger mod using the bike battery, but it is too much of a pain.
So instead I got the "Zagg Sparq 2.0
", I can charge my iPhone 4 three times over (also works for my iPad 2). It was Rs. 4000/- (after discount) in India. There you can get it for around $80. There might be better ones available in USA, search in
3. I put the Zagg in the side pocket of my backpack and charge the phone with its default data cable. Its pretty convenient and it doesn't effect my riding
Hope this helps
