I was using a USB stick style bluetooth that plugged into my rear console aux line. This was "sufficient" until my 6 year old snapped it in half while sitting in the middle seat.
Not to be dissuaded, I looked for a more "integrated" solution. Enter the Pure Electronics Bluetooth receiver. Full 2.1 + EDR bluetooth with the APTx codec means high quality audio. 12volt input makes for easy hookup with no messing around with power adaptors or any other nonsense.
So using Roskinc's great disassembly videos
I yanked out my rear center console panel which already had the two cigarette lighter jacks and the aux jack factory installed.
After pulling this, I got busy with the soldering iron.
First step was wiring 12v to one of the cigarette lighters. This is easy as you can solder directly from the bluetooth receiver PCB to a couple of points on the cigaretter lighter housing with only a few inches of wire in between.
Then I had to crack open the AUX module and using a meter to determine what was left channel, right channel and ground, soldered in some scrap RCA cables and drilled a hole out the back of the module so the RCAs could jack directly into my shiny new Bluetooth receiver. Finished up by mounting the PCB to the top of the AUX module with a little double sided tape and...
Next step is to take that new assembly and wire it up to the car.
Then snap the cover back in. Yes that's the same pic as the before picture. Point being that externally, there's nothing to see here. Super clean, super stock.
Turn on the car, pair it up with your phone...
Then you're in business!
The verdict: At $20 this bluetooth module is a STEAL. Sound quality is excellent! And the convenience of not needing a stupid cable into AUX is amazing!
I picked up my Bluetooth receiver by Pure Electronics on eBay from a seller named Curious Provisions
but you can pick up the same module from Parts Express
when they get them back in stock.
