Hyundai sonata xm radio now saying antenna when turned on

If you can get access to under the antenna check that the wiring plug is fully inserted.

Check your car radio antenna

It means the system does not have any antenna signal. Check the antenna wiring.

I have a 2008 Sonata with satellite radio issues also. Everytime it rains and I have to do any traveling in it, the storage box located in the trunk floods and shorts out the receiver,LIKE OVER THE WEEKEND!!. This will be the fourth replacement and they (Dealership)still cannot fix the problem.

Same problem here. I repeatedly complained to XM but got no reply. I listen to XM in 2009 Sonata and it was just as bad.

XM is better than AM. Much worse than FM.

un plug the xm antenna and plug the radio antenna in by it self you should get radio signal

Buy a subscription.

The 2008 Sonata does not come equipped to plug in a separate MP3 player. The MP3 on the face of the radio/CD player refers to the fact that the CD player will play MP3 files. If you want to play from a separate player, you will have to add an FM modulator or something similar.

it might be the signal is out of range gotta love xm signals once detects the signal things should go back to norm
find xm antenna try to follow back to unit see if it just came loose from bumping it

a good reset way is disconnect from power let set for a minute or 2 and then plug back in

radio id should be xm compliant the sterio your using to push the sound you need that id
