Tom Tom Power Supply

[Nightrider]

I asked my dealer to connect the Tom Tom Rider power cable to my 1200GS. They conneceted it behind the accessory socket. GPS works fine but the bike battery keeps draining because the computer stays on even when the bike is switched off and the Tom Tom removed. BMW tell me that something in the Tom Tom connection is "telling" the compuetr to stay open and is therefore incomaptible with teh BMW loom. Any ideas guys? I know that BMW try to have you buy just their own stuff but this is ridiculous. help needed please!

Firstly welcome.

My TomTom Rider onboard lead is also spliced into the aux socket and I have had no problems with it draining the battery when not in use. The problem I have had is with the software updates telling the canbus to ‘switch off’ the socket intermittently. This problem is well documented on here so be prepared to sit back with a cuppa and do a detailed search.

You may need to check with your dealer re the current software update present on your bike. One of the updates (Version 6?) was specifically designed to stop the battery draining problem. Apparently the newest software update (Version 7) solves the problem of the intermittent switching off, although I have gone down the route of having the aux socket wired to be ‘live’ which has solved my particular problem.

Welcome Nightrider

Sorry to divert the thread but was wondering if Tricky could expand on how he managed to get the accessoriy socket to be permanently live. Would be a lot easier to charge the mobile and Ipod when parked up.

The power lead for the TTR remains spliced into the aux socket lead (although now done to a higher standard than the bogge-job done by the dealer ).

The aux socket is now wired directly to the battery (with it’s own fuse) and this remains ‘live’ and available to power anything you want it to, regardless of whether or not the ignition is on or the engine running.

Don’t leave it powering anything too consumptive for to long or you risk a flat battery.

Hope these pictures help.

I haven't used the accessory socket

I took mine straight from the battery (in line fuse) no problems with the battery so far.

Bodged it myself

I soldered the Tomtom power wire to aux socket (April 05 bike and no software updates according to my dealer) and have no problems. When I turn on the ignition the TTR turns itself on and shuts down with the ignition off. If I turn on the TTR before the ignition then it remains on whatever I do with the ignition. Not sure if this then keeps the aux socket live and would then drain the battery.

I don't know if this would be of interest but I have bought a device (wiring connections) called a 'Skullcandy Jacked' from AdvancedMP3warehouse which allows you to connect a MP3 player and the TTR bluetooth module to your own headphones. (I use sony's fontopia in ear sound isolating). Means I can listen to my 'tunes and the TTR instructions / speed trap warnings at the same time without resorting to complex intercom systems. You can also use it to connect mobile phones (as they do a variety of connections) in lieu of the bluetooth module. The device has a microphone and inline volume control so that you can adjust the volume of the MP3 player. I had to make a small adjustment to the connector to the bluetooth module - connector plug pushed in too far - but overall works brilliantly and cost £18 including postage!
