Proper connection of a non-BMW provided GPS receiver to specific BMW plug

[Grumpy Goat]

One comment about the CanBus.  On my S1000XR, the BMW Nav looses power immediately upon turning off the ignition.  The Zumo XT mounted on the BMW GPS OEM mount does not loose power immediately upon turning off the ignition, it takes a variable length of time, 30-60 seconds.  That means the CanBus recognizes the BMW Nav as a GPS, but it only sees the Zumo XT as an accessory connected to the electrical system.

Hmmmm ... that is not the behaviour on my RS with its BMW GPS Prep. 

My BMW Nav VI does not lose power immediately after the bike is shut off. It does its countdown, and I can elect to keep it on. The behaviour is the same as on my Tiger where the CAN-Bus system is bypassed, and the Nav VI is powered directly from the battery, via a Healtech Thunderbox power distribution module. 

In other words, on both my bikes, the Nav VI's own battery power controls its shutdown after the bike is shut off, and the CAN-Bus system is not involved.
