A:Answer It’s the same cost; just be sure to pick the front and rear install option cause it affects the install time that’s scheduled. Make sure you take a screen capture of choosing the right install cause I think something’s wrong with their system - local store usually tries to tell me they need to postpone because I chose the single install. If the system doesn’t let you pick, write it into notes and either stop by the store and talk to the installers (not customer service, they’re clueless on car installs), or call the support number after you place the order. Be sure to order any hardwiring cables along with the cam cause they never have them in stock at the stores.
