I need to install a motion detector but I do not want to void the warranty. A cannot find a dealer to do the upgrade. Any advice?

 

does it have the factory security system or just the keyless that beeps the horn on the second lock push?

unless the factory security has an available input for another sensor or has an existing impact sensor to tie in to you will need to have an aftermarket security system installed by a local shop.

shouldnt void your warranty to add an alarm. might even net you an insurance discount.
