Juvecu, I want to use my TomTom GO 530 that I normally use in my car. I've seen waterproof cases and mounts on Ebay but need to suss out a power supply for it and thought I could use either of the two connectors at the front of the bike. The GO 530 uses a mini usb and runs on 5V. The plan was to utilise the Aux Connector under the RHS, then solder or splice in a power lead for the GO 530 off the internet.
