I wouldn't replace anything until I tried this: disconnect both battery cables from the battery, and hold the two cables together for several seconds. Then, reconnect battery and try it again. This does reboot the modules in the car, and often solves this issue. I'd definitely do that first, since it's free, easy, and quite often successful.

Did not work
Expert:  Jerry Newton replied 2 years ago.
OK, like I said, it's the cheapest and easiest thing to try first. It is possible that the voltage spike damaged the radio. Some diagnostics are in order, if this were in my shop, I would be checking power and ground circuits right at the radio connector, as well as checking data communication circuits to make sure they're working, but then? Yes, it's probably a radio failure.
