just asking what is the retail price on this alarm system w/o installation?

 

If you have a 6 speed you might not need to get that one. You can go with a 690 which has all the features of the 791 but without auto start.

 

2Nos is right about the 791, no point unless you want the remote start for an auto. Retail is typically 499.00. Bring it to someone who has done a Z before. Directed's wiring schematics are kind of wrong, especially if you have a roadster. Add the GPS to it as well, worth the money. GPS retails for about 499-699. Cost on both is about 200 for the 791 and 400 for the GPS.
