You are entitled to be reimbursed by your insurance company under your property damage claim, for items damaged in an auto wreck. The most important thing is to be able to provide the documentation necessary to get that reimbursement.
You'll want to take photos of the damaged objects, and provide documentation of the price of the damaged items, such as a receipt or going online and showing what the cost of the ipad or gps would be. Typically that is enough information for the insurance company to complete their file and get you reimbursed.
You also want to make sure you don't sign off on your property damage claim until all of those damaged items have been accounted for first.
