I had a problem before with my 1998 firebird where the radio locked and I had to get a code to unlock it now it is locked again and I don't have the manual to get the instructions to unlock it but I do still have the code.
read the instructions manual.
One would be able to find installation instructions for an under cabinet radio on the owners manual when they purchased said radio. Another place to find instructions would be on the website of the company that made the under cabinet radio.
the power has been disconnected for too long of a time and the security system on your radio was activated. look in your owner's manual for a keycode to unlock it.
Tune the radio to channel 0. The XM code will appear there.
If your radio is locked and you DONT know the passcode then you need to call Acura....but if you do know the password...then you should enter it
Have you checked your owners manual? If you know the code it is easy. If you don't have the code go to this website for instructions. radio-code.com/GM-Pay-Page-radio-code.htm
the radio owners manual that came with it, a install harness with instructions 2 hours,twist connectors, and understanding.
Many radios have an anti theft feature where if power is interrupted like when a new battery is installed the radio will be locked and will not work without an unlock code.The dealer can unlock it for you, and you might be able to find it on the web somewhere but i doubt it.The idea was for you to set the code when you got the car using the instructions in the owners manual, however nobody ever does.Thats why the second unit did not work either.
It is not, but thanks for the concern.
I had to go to a dealership to get the radio unlocked, also the cause; ( radio locked) was Battery Failure. After I puchased a new battery I found the radio use to be locked.
A Ford radio usually will become 'locked' after 10 invalid codes have been entered. In the beginning, the indication like "- - -" or "Wait" may appear on the radio's display. In this case leave the radio turned on for 2-3 hours. The locked state will reset and you will be able to enter the code again. However, if 10 attempts (or more) have been made, the radio will go into the 'LOCKED' mode. Waiting will not help in most cases. But there is a trick that you can use if your radio says 'LOCKED' or 'LOCKED 10'. If you see 'LOCKED 13' or 'LOCKED FOREVER', unfortunately, this will not help. To unlock the radio if it is says 'LOCKED 10': 1. The radio is turned off. 2. Press the '6' (6th radio preset) button and hold it. 3. Do not release the '6' button. Turn the radio on while holding the '6' button. P.S. This will not help with all radios. Some systems may not support this reset trick. WARNING: After this trick is done, you have 3 more attempts. If you use them up, you will not be able to unlock the radio yourself again. NOTE: Some radios say 'TEN' instead of 'LOCKED'. For these radios, turn the radio on and hold SELECT and MAN buttons together. You will have ONE additional attempts (when it is used up, the radio will say 'TEN+').
