Any suggestions on how to reset this?
I've seen the methods for other makes by removing the Backup fuse but this has not worked for me. I also do not have preset buttons so using that method to retrieve the serial will not work.
Does anyone have any information pertaining to the 2004 TSX that will help me fix this issue.
You have entered the radio code incorrectly too many times and the head unit is now locked.
You can either a) leave the key in the "ACC" position with the head unit ON for one hour and COdE will appear on the display allowing you to re-enter the code or b) disconnect the battery for a few moments (making sure all electronics inside the care are OFF first) and then trying to reconnect.
I believe Honda has gone to a web retrieval for unlock codes now. If you don't have the serial number to the unit then there is a modified 1 & 6 technique for units with navi (using different key combinations). I used to know it by heart (I worked on the Honda side for a while) but I have forgotten it. Acura Client Services can walk you through the retrieval process but there is a way electronically to get the number from the radio.
Otherwise, look in the glove box for a small white sticker with a long number on it. This will be the serial for the radio. With the serial you can call Acura Client Services and they should have the unlock code. The sticker may also be in the center bin.
Good luck and WRITE THE NUMBERS DOWN!
