Procedure requred:

Push talk button and system beeps
Say "phone setup"
Push talk button
Say "pair"
Listen to all the instructions
Push talk button
Enter "0000" as your pairing code as HFL system recognizes it really well.

Ensure Bluetooth is active on your phone and it is in discovery or search mode

Select HandsFreeLink when it pops up enter 0000 and it will say successfully paired and ask you to enter a name for the phone

Push talk button

Name your phone

Done

First, the new HFL bluetooth module you bought, is it the same part number as the one that failed? If yes, return it and get a a different part number. The original parts have been failing in all cars. If you have the same, it will fail again later on. I talked to my Acura parts especialyst and he send me the correct replacement module that replaces the one that fails.

If I remember well, when the BlueTooth module is disconnected we loose the voice commands for radio, A/C, etc.

What I did to keep the module connected, use voice commands, and avoid the battery drain, I installed a micro-relay that disconnects the power from the module when the car is OFF. The relay is powered by the AUX power and the Normally Open (NO) contact interrupts the permanent power wire. I used this wiring for several years without any problems. Even after I replaced the BT module years later, I still have this wiring configuration in place. If the new module goes bad ever, I will not have a battery drain.

The factory wiring keeps the BT module powered 24x7, that is part of the problem in the electronics failing. This relay wiring switches the module ON only when the car is used, therefore it should extend its life.

I was thinking of doing something similiar at one point but never got around to it. Thanks for posting about it. I'm really surprised they thought the BT needs to be on 24/7.

That is right. With HFL, the parasitic draw is 0.2 Amp. Without it, it is 0.02 Amp. I am much more confident with the battery when HFL is gone.

I took mine to the dealer and they said my HFL was bad. $80 to disconnect it or $999 to replace it. I should have said I will disconnect it but I let them do the work. Will look and see if I can find this unit from OEMAcura or Amazon.
