If the radio in Your 2007 Mazda CX7 fails to function and You are sure it is powered on, the first place You should start looking is the fuses. Depending on which Audio package Your vehicle came with You may have 1 or 2 fuses that protect the radio. If You have a BOSE system You will need to check in the underhood fuse panel, in position # 10 You will have a 30 amp fuse labeled BOSE. On the BOSE and standard Audio system You will have another fuse in the interior panel. This one is 15 amps, located in the # 11 position and labeled ROOM. If You replace either of these make sure to use one that has the exact same amperage rating so You dont damage any of the electronics it protects.
