I have the rail system. There is a hole in the headliner with wires inside it. Does anybody know what the hole and wires are for?

 

I know what this is.....This is a pre-wire for a bluetooth device that mounts in on of the storage bins. It won't be out until the end of July or August. Brandmotion has this product. www.brandmotion.com it is called the blueconnect. This prewire system allows you to plug and play this device with a bluetooth phone and when you recieve a call, it auto mutes your stereo. Pretty sweet. I am thinking of getting one. I did just order the Magellan integrated navigation system from them (well on ebay) i will get it tomorrow. can't wait.
