Problems with the HFL in the acura MDX

I recently purchased an Acura MDX 2007. After taking the car to the dealer because the HFL button wasn't working the technician said that the whole system has to be replaced (microphone and control module unit) with a total cost of 1,200. Do you know if someone else has seen this issue in his/her car? Do you know if we have any other options to get this fixed?

Super easy to fix yourself. Sit in y our backseat and pull as hard as you can on the air cond controls. Pull it straight back and hard enough to make you think it could break - it won't. You'll see the top pops off easily and the bottom needs a little coaxing, just keep pulling it straight back and massage it when it needs it. Once you get that off, there is a little black box right there with a bluetooth symbol on it. The cable is really easy to remove, if you have to use force, you're doing it wrong. There is a little pressure button on the cable that will release it from the unit. That unit is what needs replacing; this is a common problem among MDX's, apparently. Anyway, you can get this part on ebay by searching for "07-11 Acura MDX HFL" without the quotes. They run about $140, it looks like.

Good luck!

    Today, I pulled off the back seat air and entertainment system cover and found the module. After unplugging the module and replugging, it has been working just fine. Will prate if the unit fails and it is not just a plug in problem. The above solution comment was extremely helpful. Thank you so much. btw, I have a 2008 MDX.

    Just came back from dinner and the Hand Free Link was inactive again. It must be the Bluetooth module.

    So...after doing all the above, I ordered a module, P/N 39770-STX-A011-M1 for my 2008 Acura MDX with navigation and entertainment, from the acurapartswarehouse.com for $187.45 plus shipping ($13.15) for a total of $200.60. When you pull off the cover, the part number is clearly visible on the module. Plugged in the new one and voila, the Hands Free Link works just fine. So if you think it is worth $200 to have the Hands Free Link, it's not that hard to switch out. Follow the instructions from the earlier comments for pulling off the cover. Good luck.

I had the same issue with HFL went dead on me couple days ago. Today 11-14-13 I had oil changed at dealer and Asked dealer and they wanted $180 to diagnostic and use it toward repair cost if $450. Forget it no need. Search posted solution 1. Just 10 minutes ago pull the rear ac console and whola the module is pretty hot. First I unplug the cable then plug the cable back and boom the lady's voice came up. Setup the bluetooth again and wow it works again so I did not have to replace the module yet. My 2008 Mdx is fixed.
Took photo of module but don't know how to insert photo but here's the part number info I got
from 2008 Acura Mdx

    I'd like to add additional information and to clarify few things to answer#2.

  • Kgb_2009 Aug 05, 2014

    After I had reset the HFL, it worked for a little bit then died out. I ends up replaced the battery and stop using HFL until Saturday 8/2/14. I finally found a reasonal pricing sold at Amazon plus shipping came ~$190. Disconnected battery. Installed new HFL box. Bluetooth works like a charm. Also just to clarify before pulling the heater console open ensure to open the center console cover then pull otherwise no gripping space. Anyhow good luck to all.

I have an acura MDX 2006 - fully loaded. The problem i have is that suddenly the bluetooth has stopped working. I checked with the dealer and they quoted about 1000 to replace the module. can anyone please...


Do you mean the Hands Free Link that pairs your phone with the audio system? If so, then it sounds like your HFL board has died. I have the same vehicle and the same problem. A new board costs about $200 online (part # 39770-S3V-A61ZB; there's also a 39770-S3V-A61ZA but it costs ~$80 more and as near as I can tell the only difference is that it's a different color, but since you can't see it, no sense in paying extra for that) and is located in the compartment in the ceiling just above the rearview mirror (where the two overhead lights, sunroof switch, and OnStar controls are). It's not terribly hard to pull out and replace the board yourself (there's a guy who posted a series of Youtube videos for doing it on a TL, but it's virtually the same procedure on the MDX, search for 'HFL removal and install").

I don't have the code for the bluetooth system for my Acura MDX. Is there a reset button for the bluetooth setup?


Hi,

If you got an owner's manual with the X, check page 172 for "clearing the system".

If not, the manual says to Press and releas the top of the TALK/BACK button. After the beep, say "System." The HFL will respond is, "System options are setup and clear." Press and release the "TALK/BACK button. After the beep, say "Clear." This process will clear all paired phones, all phonebook entries , and clear the passcode. Is this what you would like to do?" Press and release the TALK/BACK button. After the beep, say "Yes." The HFL will respond "Preparing to clear all paired phones, all phonebook entries, and the passcode. This may take up to 2 minutes to complete." Press and release the TALK/BACK button. After the beep, say "OK" to proceed or say "go back" or "Cancel. If you say "OK," after a short period of time, the HFL response is, "System has been cleared. Returning to the main menu."

Good luck.

Changed battery of my 2002 acura mdx, need codes for radio nav


You need to get the serial number off the sticker attached to the radio and nav. It will require pulling apart your dash. Call an Acura dealership with that serial number and they should be able to provide you the code. Or you can take it directly to the dealer but you will be charged labor.
