Adding a USB port to a motorcycle as to power / recharge an iPhone

Today added a USB charging port to my BMW F800GS.

The reason is that I need some type of navigation on the motorcycle but won´t use it enough to invest in a motorcycle specific navigation device which tend to be very expensive. So I wondered if I could use tomtom or google maps on my iPhone for the task.

I encounter 3 issues to make this work:
1) How to mount on the motorcycle: see next post:

2) How to hear the instructions:  Got a bluetooth for the helmet. See post:

3) How to power the iPhone for long trips.

After investigating for a while on USB ports, I decided on this one:

Because:
- You just need to connect it to a 12V source
- I can adapt it to connect to the BMW´s Canbus as to turn on and off with the motorcycle. (No switch needed and no fuses needed)
- It´s weatherproof
 
As to mount you need a BMW Canbus cable. You can use part number 80 00 0 611 656.

Instructions to make it work with CAN-Bus (sorry, no pictures!):

1. On the BMW CAN-Bus connector you can cut off wire 2 - it isn´t needed
2. Soldier the black wire from the USB connector to wire 1 on the BMW CAN-Bus cable
3. Soldier the red wire from the USB connector to wire 3 on the BMW CAN-Bus cable.
4. Waterproof the connections - Heat shrink them or use PVC tape.

Instructions to mount on BMW F800GS

1. Open the top cover of the BMW F800GS (that covers the battery
2. You will see the GPS CAN-BUS connector right next to the battery in a holding clip. (it has a plastic cap)
3. connect the CAN-BUS plug with USB connector you made above.
4. Route the wires to the handlebar.
5. Mount the USB plug on the handlebar

And Done!
