Hi Sir or Madam, welcome to Pearl.com. I'm acramstr. And I will be assisting you today.
Before you blame the radio lets try this. Pull the back of the center console off . (open doors and pull starting at the top vent ) It just clips on . Under the rear cover bolted to the back of the console box you will see a black box with a gray plug. This is the Bluetooth unit. Unplug it and see if the drain goes away. We have many problems with these units shorting and draining the battery. Also check the a/c compressor relay they stick and drain the battery as well. to check this start the car and turn the a/c on You will see the end plate spin with the a/c on and when you hit the "off " button it should stop if not the relay is stuck. Try these first before removing the stereo. This car has a can system and if one unit stays awake everything else does as well this could explain the stereo resetting.
Thanks for your response.
It is not 100% clear what you mean by the "back" - that could mean the part of the console that extends to the back seat, the back of the nav, etc.
Can you make it very clear? And how much force am I applying to pull here? Do I benefit by using a plastic pry tool?
This seems to have worked!
Next steps to get a replacent hfl? Any tips for that?
There are dealer's that sell parts at wholesale prices on the internet that are the best deal.. Here is one US dealer that sells them http://www.acuraoemparts.com/delray/jsp/home.jsp the part number is XXXXX it should cost about $225.00
Also I would call Acura and ask them to help with the cost as this is a known issue with these vehicles. Please remember to only rate my answer when you are 100% satisfied.
