HFL is in use constantly. Cannot disengage!
I got a few back-to-back calls Saturday night. After which the HFL just froze in the "IN USE" mode. I cannot play the radio or anything. It stays on all night and today is Monday. I have the Nokia 6820 and I've been using the phone with this system since I purchased the car without a problem. Even with the phone away from the car, and the car being off all night I'm still having this problem. I've called my service advisor and he didn't know what to do. I called the dedicated HFL service number and they told me to take it to the dealer and advised me not to disconnect the battery. Does anyone know what I can do?

If that doesn't clear up your problem, a trip to the dealer seems in order.

I was surprised when the service manual indicated that the interior light fuse had a lead to the HFL control unit. It almost made me wonder if they didn't design it that way on purpose so you can force a reboot of the HFL system without disconnecting battery or having to reset the radio, etc, etc. Dumb luck or planning to deal with a known failure I don't know but I was happy when I pulled fuse #6 of the interior fuse box, replaced it and found everything back to normal.
I doubt anyone in this thread cares any more but I wanted to throw it out here for the next person that googles for it.
A few key word for the bots:
HFL lockup HandsFreeLink disconnect battery pull fuse "Phone in use" stuck
P.S. If you find a problem like this and figure out a workaround please provide details so others know better how to deal with it. Just saying "I yanked a bunch of fuses and finally found the right one" doesn't do anyone any good.

I had this issue and disconnected the battery terminal... I actually reconnected it 10-15 seconds later... the problem cleared and I didn't have to enter any codes for the radio or navi.

First try to delete the phone. Look in your owners manual under hfl. About page 60? then follow the directions on deleting the phone. Once deleted, try a pair the phone again. If you still are having problems vistit the Acura/honda hfl website at www.handsfreelink.com for further info. I hope this helps.
