OK, I did some reading online. Found the HFL module up under the map light console. I unplugged the HFL module and let it sit for a while to dissipate caps, if it has any, etc. Then, plugged it back in. Still doesn't work.
I called Acura service and they said the units fail. So, I went looking online and only found a couple new ones at ~$400. Ouch.
So, looking for any advice as to whether or not there is an alternate, refurbished, etc., that I could get for less. I'm not sure it's worth $400 to put an old tech hands free phone back into a 13 yr old vehicle.
