Hi guys, Got my PIP over the weekend and paid additional for a factory alarm to be installed tomorrow. However, some people told me I dont need it for the prius, also the dealer told me they will have to drill hold for the alarm light which I get freak out. Any one of you had it installed? Does it worth $400? Are there other aftermarket options? Please help since I am taking my car in tomorrow. LT26i ? 2
