So I would much rather buy this stuff off of amazon then to pay MSRP at a stereo place. What else do I need to purchase with this alarm/remote start combo in order for it to work? Just this DBALL interface modile that Viper suggested? Thanks!

 

I just installed the Viper 5706V to include the following sensors:
DSM250, DBALL, 508D, 509U, 507M, 506T, 513T, & 520T. Make sure when you have this installed BY A PROFESSIONAL that they use the High Current side if you have this much shit attached to it and also ensure to have the "Tilt Sensor" (507M) set so when it triggers it tells you on the remote and via the phone app if you go with that setup.
I purchased my setup thru Best Buy as i have a part time position with them.

I would recommend at least the Ultrasonic sensor (509U) and the Tilt sensor at a minimum... Ohhh... You must have the DBALL in order for the Viper and Acura systems to interface and work together.
BTW... my stock Acura remote will also engage the Viper security system.
