Here's a video describing an issue that I started having recently with my 2008 Acura TL base sedan with the 5speed automatic transmission without navigation. The Bluetooth system began displaying the message ''Booting Up'' in the MID, along with ''No Information Available''. Due to the cold weather and slightly longer start times from the HFL module draining the battery when the car was off, I decided to unplug the module and to live without Bluetooth for awhile. The replacement HFL module is $180. I hope this helps anyone trying to fix their own Acura TL with this problem.
