BMW very kindly supply you with a Can Bus Supported Auxiliary Port on a range of their bikes that means you can easily wire your Sat Nav into the bike, meaning it will be powered from the battery of the motorcycle, however when you turn the bike off the Can Bus System then shuts down the power to the sat nav a short time later resulting no power going to the sat nav cradle and no battery drain.
Well that is the theory anyway, however some users have experienced battery drain and blame this set up, claiming that the Can Bus System isn’t compatible with their Sat Nav. That may be and BMW won’t say officially if that may be the case, stating only that their ‘Sat Nav’ port is for use solely with their Navigator System, and why not if you want to be 100% sure that everything is going to work beautifully together then you need to hand over £700 for the privilege.
Just keep a close eye on your battery levels for the days following installing your sat nav, and hopefully you will not be one of the examples.
As stated above the port we will be using what BMW refer to as their Sat Nav port, it is what their Navigator System plugs into. The Navigator is a re-branded Garmin Zumo, with BMW software installed on it, but removing this software and it is still a Garmin.
BMW also supply a plug, named something like ‘3 Pin Repair Plug (multi use)’, some dealers will refer to it as a ‘Sat Nav lead.’ The part number is 83300413585. I ordered mine from ww.motorworks.co.uk and the part number was ELA13585. I was unable to purchase it direct from my BMW dealer but with motor works it arrived the next day, and was slightly cheaper also!
This plug gets attached to the battery wiring lead that is supplied with your TomTom. This plug then plugs into the port on the motorcycle, resulting in automatic powering and shut down of the TomTom Cradle.
I have uploaded a quick video to YouTube Showing this in completed install in action and the successful powering up and shutting down of the sat nav in conjunction with the bike. You can view it here :
It is a simple process that only requires 2 wires to be soldered together :
Take the ‘Fake Tank Cover’ off the bike to reveal the battery compartment :
2. Here you will see the battery and the Can Bus Connector (in this picture it is the socket underneath the white connector. It is held in place in a clip and has a cap on the end that simply pulls off :
3. Here you see both wires, the black one being the TomTom Power cable, the socket you see at the end of it plugs into and thus powers the Sat Nav. The yellow is the BMW 3 Pin Repair Plug (multi use) as supplied by BMW.
4. On the BMW 3 Pin Repair Plug (multi use) you will not that the 3 wires are number, 1,2 and 3. Wire 2 is not required so you can cut if off, or just ignore it and heat shrink it later (this is the option I went for).
5. Strip back the red and black leads of the power cable and wires 1 and 3 of the BMW cable.
8. Solder the Red TomTom wire (live) to Wire 3 on the BMW Connector.
For my bike I considered the following mounting options but the high and low middle options obstructed the clocks. I am also looking for alternatives and more secure mounting options which I will add info on as I come across them :
