Car broken open without TÜV

Hello@all With a friend of mine the car was broken up last night. However, since 06.2015 the car no longer has a TÜV he would have had to check up until 30.07.2015. Now the acquaintance has afraid that the insurance could make worse because of the missing TÜV. Should he now worry or not Navi and Airbag have been stolen. Thanks already for your help.
