Radio has no power, all other electrical fine
I have a 2007 Sonata. The radio has no power. This happened after a bad battery boost (reversed polarity)
I swapped the radio with another one. It's possible both radios are dead, but I think the problem is something else. I've checked the fuses in the fuse-box that's in the dash, they seem okay. Is there something I am missing?

Take a DVOM and check the power at the connector to see if there is 12 volts
!2 volts should be at the keep alive for memory
And 12 volts should be there when key is turned to "on" or "acc"
Check the ground to make sure there is a complete path/circuit for the radio to work
Good luck

Did you check all the fuses?
Check for voltage at the power to the radio
Both the keep alive memory wire and ignition power
If you need a new radio then you can always put in an after market radio??
On my 2001 Elantra, I bought a cheap radio for 30 dollars and put it in myself.
