installing a cat2 system alongside an existing cat1 system?
 

am i able to use a cat2 system (toad sterling excel: http://www.toadalarm.com/productdeta...p?ProductID=50) alongside an existing cat1 system (sigma m30) without it affecting the cat1 status of the sigma?

i was thinking of using the toad as an extra layer of security in order to start the car so i'll still need to disarm the sigma as normal but without the toad in range, the car won't start..
