Radio no sound!

You need to start a new question, and please be sure to include the engine size and mileage. This was a conversation between two people. None of the other experts are going to see your addition or have a chance to reply. That does you a disservice. Also, a 2006 model radio is totally different than the 2001 in this question. The model number that was discussed here was only produced for one year, and there was a much better model that was a direct replacement.

If you have a remote amplifier, that is switched on through a digital signal from the radio. Either the radio or the amp could have a problem. There could also be a blown fuse for the amp.
