Introduction: Add a Bluetooth Adapter to Your GPS Device
I needed a way to hear my cheap a$$ GPS under the helmet on my motorcycle and didn't wanna fork over 2x the price for a "motorcycle ready" GPS device so I made it myself.
This may be interesting to bikers a well!

GPS + bluetooth
Step 1: Open It...
When you CAREFULLY open your new TomTom One you'll notice that there is a battery and a speaker on the back and all the electronics on the front side.
Step 2: Radio Shack Bluetooth Adapter
Buy a bluetooth adapter for non-bluetooth cell phones like this one from RadioShack ($30) that even comes with an adapter for nokia phones with a tiny receptacle 2.5mm headphone jack!
Step 3: Drill a Hole...
Drill a hole in the bottom of the back really close to the back wall. You have about 12mm to the battery so be real careful.
Step 4: Connect...
Duplicate the two wires going into the speaker and connect them to that small phone jack and glue it to the back wall after you stick it through a hole you just drilled.
You can do this by using a new two pin molex connector. Just attach two more wires to it.
Step 5: Plug In!
When you put it back together it will look like the jack was there straight out of the factory.
Step 6: Use With Your Cell Phone Head Piece
Now you're ready to pair it with your cell phone bluetooth ear-piece and use it under the helmet.It works awesome!You just made your self an upgrade to a $300 more expensive device that you can mount on your motorcycle.
Enjoy not getting lost!
