Sorry about the broken window but on the up side you still have your car stereo equipment. Check with your insurance company and see if they have a flat deductible for the glass it might save you some money. Time for you to add that glass breakage detector along with the microwave sensor to that "over priced" alarm lol Seriously, I'd have some major beef with the install shop, this just proves my point that shops love selling the "idea of security" but the product will only be a deterrent and nothing more. Goodluck with the "theif hunt"
