I'm a new owner of a 2007 and so far I really like it. I was trying to hook up the Bluetooth and it says "system is locked." I don't have the previous code so I guess I'm asking how do I reset it to hook up to my phone. Or should I just unplug it and don't bother before it drains my battery?

 

You don't need previous code, press and say "set up" then wait for the prom to ask a bunch of options then say "pairing" then HFL will ask you to make up a four digits number lets say "1111" then you go to your phone and enter the pin in and you are done.

 

So I tried it. As soon as push the button it says system lock please say the passcode. I tried saying "set-up" and "phone set up" nothing happens.

 

that strange, I bought all 3 acura used and on all of them never ask me for any "pass code" if you still have trouble the last thing is to bring to the dealership and may be they can reset the system.

 

Here is the my manual for a 2006 TSX: https://dl.dropboxusercontent.com/u/...s%20Manual.pdf

I not sure; but, I'm thinking you might have the max number of phones already paired to the system (6 total). The handsfree paring stuff starts on page 211. On page 224 are the commands for "Clearing the System" and it deletes all passcode, paired phones, address book info. I'm not 100% sure too many pair phones is the problem; but, it wouldn't hurt to clear and start the pairing fresh.
