Great information guys...thanks!

Judging from what you are saying, I am best to set up the proximity sensors with the top down...as that is really why I wanted that sensor. Easier to leave the car with the top down, if you know that an alarm will go off if someone reaches in.

After setting it up with the top down, I imagine the warn away, would not be as sensitive with the top up and windows up.

I will take some time and experiment with different settings.
