GPS tech (Garmin, Hammerhead, Wahoo, RWGPS, etc)

this any use? i imagine its compatible with other brands ( if you cut off the Nokia plug and soldered on the relevant one for your phone...?)

these are good too...only £17.99....way cheaper ( and more waterproof) than the Dahon ones....fits a Nokia N8 as well..

I used a USB battery backup for Dunwich last year which worked very well, recommended by Scott. it takes 4 regular batteries, plugs into the mini usb on the garmin and although doesn't charge the Garmin, lengthens the battery time.
I'll have a look and see if I can find the details...
