I have done 120,000 in Aero's since getting my Series 3. The average per year in that time is low as the S4 was off the road for quite some time when it was rebuilt on a new chassis but went over 80,000 during 3 driving years!
I have had the GTN for exactly 1 year and have been very lax in getting it out as much as I should (put 25,000 miles or so on the Tesla since getting the GTN)but have clocked up just over 3,000 in it.
