Interesting thread on trackers. I imagine the Motability tracker would be like the standard BMW tracker in that it sends details of the last location when the engine is turned off, rather than tracking the route being driven which would be very data intensive.
I just checked where our X1 is and it’s inside the workshop of Marshalls BMW Bournemouth where it should be, having its first service today (at 18 months and 15,000 miles).
