2006 s60 rs

every car make will have there list of failed installs, it just depends who is doing it, the install is only as good as who is putting it in the car

this car is a fairly easy job, but I don't know your knowledge level, you will need 2 extra pieces as described below

use a bypass from idatalink, in your car it will be a 3 wire hookup if installed in data mode, it will control all conveinence features including factory alarm, doorlocks, and so on

you will also need a piece from DEI it is the 556U, this will bypass factory immobilizer, but you will have to loose a key
