Sounds like you cut a ground or power wire when installing the new radio. Go back over your wiring and also look for any possible shorts from your new connections to ground or power. Also, it is possible you partially unplugged a connector while working in the area. Make sure all plugs are completely seated.

and make sure he disconnects the negative battery cable from the vehicle battery before performing any electrical work on the car.


Put in the new fuse u blow up when putting in the new radio its in fuse panel


And marina is right


sounds like a main fuse or main hot lead



Changing a radio in a newer vehicle is tricky as everything runs through it. Not a job for a do it yourselfer. I was told this by a friend who's a mechanic.
