Using 2010+ HFL in 2007

Is this possible at all? I don't care if the extra features don't work, like music streaming, but I can buy one for $150, vs $500 for the 2007-2009 model

I've seen HFL around here but no idea what it is. What is it?

HFL = Hands Free Link. Basically the module that enables bluetooth phone calls through the vehicle.

Did some quick reading on an Acura TL site. The year model they were dealing with was 2004-2008, and reading through the Wiki on it, there were some massive changes to the electronics throughout the generation. Our generation of MDX is the second gen, which covers 2007 - 2013 models. The guy on that Acura TL site replaced his 2006 HFL unit with a 2004 one which spanned across several electronics changes in the year models. I looked up the parts for the 2007 HFL and 2010 MDX units and the connector appears to be the same.

If you look at the pics on the TL site, you'll see that the guts of both units are quite a bit different. Were there changes enough to make them incompatible with each other? Not sure. The part numbers are different, but the only real way to tell if it works or not is to try it.

Wouldn't you know it. I went to hook up my HFL in my recently purchased 2008 MDX Tech only to find it wasn't working.

I went into the system menu and ran a diagnostics, low and behold!

Looks like you and I are in the same boat my friend! i'm going to try and bake mine first to see if I can't resurrect it. Otherwise, maybe i'll try a newer model just to see if it'll work!

If you guys do find one for a decent price, please share. Mine is not working as well, and the baking method didn't help, so I was going to install an aftermarket kit for about 25 bucks. I think 25 bucks is worth trying, rather than paying 300-500 for an OEM unit.

The new model works very well. I bought mine from an Acura dealer in Kansas for around $200 to $225. I do not recall the exact number but was not greater than $225 for sure. The hardware and firmware revisions where different than the original unit that failed on my X. Talk to your supplier and ask for the replacement of the failed units. That is what I did and has not failed me.

What year model do you have, and what did you replace it with?

I'm not even sure the baking method would work for mine. The PCB is double sided so if I heat it up, the components on the bottom of the board are likely to fall off. Not sure I want to experience that lol

My X is 2008 and I replaced the HFL module it in 2015 after having the failed unit disconnected for about three years. I used the module recommended by the Acura dealer to be replacement of the failed units.

ok so it sounds like they put a 2008 unit back in.

Most likely, but the hardware and firmware revision was different that the original.

Can you pop open your armrest real quick and snap a picture for us? If I buy a new one I would like to make sure I got the right one. Maybe someone can check the 2010 and up 2nd Gens and see if they are the same since they had A2DP and harddrive based navi which is different from 2007-2009 models?

I wonder if the class action suit will get us new units.

Latest update from March of 2018 is that they are in discovery after the judge did not throw out the case. Signup below if you haven't already.
