I now have one of these tags - very small. There are a lot of warnings on the packaging talking about fixing it to windscreen on the "black mottled area" I don't have that in my 75 (regular mirror - no rain sensing bits) - those that have used the tag can you tell me where you fixed it please and did you have any issues with it not being read due to placement?
Actually I don't really like sticking things to the car - stickers or anything - and was considering temporarily fixing it up there (or even holding it up at the toll!) - how sensitive is this to the placement of the tag?
(I guess I'll find out next week but it pays to be prepared!
)
Thanks!
