Yeah the Infill is nice but its like $2100 and is a big theft risk. For the 2/3's the price the set up I chose, as far as theft is concerned, works better for me.
The stuff I always have gotten stolen, 4 times now despite the alarm, is the head unit.
Probably need some better security like a tazer that shoots out at crook.

Lol.
But if you got a garage and are not worried about the theft factor or money get the infill G4. Its a lot easier to install and that may be the deciding factor.
