Good luck
yea, i waited about a minute... and nothing.
thanks for the info though - i know what to test out in the near future now.

As for the "PANIC" button... some claim that holding the open trunk button will activate the panic siren... i tried holding it for 10 seconds or so, and no panic siren... any advice on this?
