Sat Nav Plug Question

[RoyF]

Evening All....

I was just about to buy a sat nav plug and lead from Nippy Normans, this one....

http://www.nippynormans.com/product...mtom-gps-into-the-bmw-harness-gar-canbuszu660

....for a 2013 GSA.

Looking at the plug taped under the frame right behind the oil cooler, it appears to have two wires going in the back, and with the cap removed two holes in the front, with the third hole blanked off. Now the Nippy Normans plug has three wires and three pins showing, before I order one and butcher it to use just the two pins I think I need, is this the right way to go about it or am I on the wrong plug? I say that beacause I couldn't seem to get 12v across the two terminals with the ignition on when I tried earlier, but that could be because I couldn't get a good connection in the pin holes. (The aux connector under the seat was fine though).

It also seems to be a bit of a complicated plug, as the wires in the back don't seem to line up with the holes in the front, wondered if it did anything more than just being a socket for a Nippy Normans type plug?

Thoughts appreciated....Thanks

Quite clearly states on nippy,s add, wires are numbered 1,2,3, DO NOT USE 2.
Hope this helps.

Yes I know it does.... but on my socket I only have two holes, one is blanked off or filled, therefore do I have to cut on one the pins off of Nippy's cable ??

I think you might have the wrong socket on the bike. If memory serves, there is another "unused" socket under there that connects to either the carbon canister (US bikes only) or a cooling fan (only fitted for some markets/applications). The correct one has three holes, for the three pins on the lead that NN etc sell. The third, unused conductor carries a pulse signal that varies with speed. Same plug/socket is used on other BMW bikes and none of them require you to cut pins etc to fit.

The one you want has a black cap on it right behind the oil cooler

The three wires are 1, negative, 2, switched positive, which is off immediately on key switch off, 3, switched positive, which remains live until approximately one minute after key switch off. Part no 80 00 0 611 656. Cost £12.00 from any BMW dealer.
This is from my experience with r1200gs canbus bikes upto 2012tc. The same part also fits my 2013 f800gs.
Hope this helps.

That "immediate on/off" line is actually a speed-related pulse signal (it only looks like an "immediate on/off" line because at a standstill it shows +12V). Once the bike starts moving, it pulses 0V to +12V. I think it was intended to provide a speed indicator to a dedicated GPS receiver for use in weak/no signal situations.
