I have a bluetooth adapter that uses the cigar light outlet, and while it works fine, I would like to find something that is hidden. Is there anything that can be hooked into the car's power and i tucked away somewhere out of sight. I don't want to use one of those cassette adapters.

 

If you don't need access to it. you could remove the centre console and located the Bluetooth unit in there are there are several switched 12V positives including the original cigar lighter. If you need access to the unit you could pass the wires through the console and into the cubby or even install a second cigar lighter in there. Very cheap on eBay. Someone on YouTube has done this. Possibly John at To The Garage but a quick search will find it.
