Actually, after checking all fuses with tester and they all tested as if they were working, my husband pulled the fuses related to radio, I think there were 4 all together, pulled them out and pushed them in again, and by some stroke of luck, just as I was looking up how to remove the radio from the dash, CD's that were in the radio began making "noise", so we got the key, turned the power on and the radio asked for the code as well as the nav system asking for the code, knock on wood, everything has been working perfectly ever since. Do not know what happened to cause it, just happy we did not need to purchase the radio at an estimated cost of at least $800. Good Luck!
