Pull the Battery Post off the Battery then the fuse If that don,t work Cut the Horn Wire To It

You need to gete the radio security code and enter it in. Just call or drop by the dealer and theye can give you the code or enter it. Should be free but your dealer may vary. When you changed the battery and lost power the radio goes into a secure mode just in case it was stolen. The code should be about 4 digets long so its not a big thing to enter. its keyed to your vin number so the d ealer may want to see that as well as your registtration and maybe a drivers licence depending on how paranoid they are.

battery dead.

Same thing happens to my wifes Tucson. If you put in a CD it turns the radio on. We have had to do this a couple times now and it works every time. Of course if there is a CD in there it won't work....as a result we make sure to always eject the CD before turning the car off. There was a recall with the brake control switch as well the radiop in the 06' are a known lemon however the unit has a reduced warranty which does not match the bumper to bumper warranty. Also the air bag sensor is a recall (I believe). The daytime headlights will stay on sometimes too for some reason which is what drains our battery, Good luck!

check to see if getting spark or fuel if no spark could be crank sensor or cam sensor have to check voltage out of wiring harness if low voltage ecm bad. Pull both coil wires off coil and have someone turn ignition no spark probably ecm. For fuel check number one plug see if wet and also listen when you turn key for fuel pump. If driving it just died on ya and battery went dead like know and you tried jumping or replacing battery.Still would not start ecm bad.

this just happened to me to. do you know whats wrong.? or how to fix

Any time battery is disconnected the radio has to have a code reentered. This is a theft prevention issue. You should have gotten the code if you bought the car new, if not call the dealer and he can provide it.

Re key less entry have no idea but could be same issue.

Hi, this sounds like a dead battery,you can try jump the battery with another car, or try another battery,

Had battery replaced on 2005 DTS and afterward the radio/NAV/On-Star would not work.(Totally dead) The dealer who installed could not locate problem. (No GM dealer in Amador County, CA). I read several forums citing this/similar problems. I checked the three fuses labelled "radio, audio, NAV" by pulling, checking and reinstalling (all three were good). When I then restarted the car, everything was once again working! Poor connection? Corroded contacts? Some mysterious computer glitch? Who knows?
