Hi I have a 03 Honda Accord ex 2.4 only had it for about a month.Radio worked but I had no code but it still was on.got the code and the second day driving listening to the radio it just shut off.The ac/heat buttons still work.I bought a factory navigaton Honda unit and tried to plug it up but nothing cut on except for the heat and ac. My original radio said 7bk0 I tried to install one o found at junkyard from 07 that had Xm.it didn’t power on but ac worked.are the radios not interchangeable or what.i hope I don’t have wiring issue.if so what tool can help me find if it does or doesn’t.
All fuses are good
