    This adapter is a device that plugs in your auxiliary input, and what it does is it gives you partial Bluetooth capabilities in a car that doesn't come from the factory with Bluetooth. It allows you to wirelessly access and play the music they have on your phone through your car stereo, so no more wires to connect. Your phone will automatically connect when you get in the car. Just to be clear here, this will give you Bluetooth for music only. This device will not allow you to take phone calls through your car stereo, more for wirelessly connecting and playing music from your phone through your car stereo. The way that it works is the adapter will plug into the auxiliary input and it'll sync to your phone. Once the Bluetooth is synced and it can remember up to four devices, a device will automatically pick up your phone moving forward, and you'll have access to your music. This will work with both the factory and most aftermarket stereos, as long as you have the 3.5-millimeter aux port to plug into. The adapter does run off of a battery, but it has a built-in rechargeable battery. The battery will last up to eight hours on a single charge, and when it does need to be charged, can use the included USB cable to charge it back up. This thing all works from the Control button right here in the middle. Press it once to wake the device up, and it'll blink blue to let you know that your phone is connected. To turn the device off, you press and hold for five seconds. The red light will blink three times when it turns off. In order to play your music, you press the Control button once and press twice to skip to the next track. As far as price, you can expect to pay just after the $50 mark for this adapter. It's going to come with a device, an extension, and the USB cable to charge the device. When it comes to the install, if we want to call it an "install," is a one out of three wrenches on the difficulty meter, and it's going to take all of five minutes to get done. All you're looking at needing to do is after charging the device, you'll then plug into the auxiliary port, carrying your phone with the device. Select the aux port source on your radio and play from your music. This adapter will work with the 2005 and newer Mustangs that don't have Bluetooth from factory.

        The Bluetooth device is said to fit Mustangs from 2005. However, I know of the power outlet in the center console but it does not have the 3.5 input jack. I can only believe that the beginning models of 2005 Mustang were not equipped with the jack. When I push the "AUX" button on the radio, I get the "NO AUX INPUT" flash on the radio.

            It worked at first...

            I bought this so I could stream music from my worked for about a week and then the sound GREATLY diminished and it would turn off and on on its own, fully charged or not it didn’t matter. I ended up having to get a different kind on amazon and so far that one does more than this one and the sound is great!

            Great Product

            Item was plug and play and what a difference. I had previously used a cable for my music from my phone. This has given me the freedom that I enjoy on my newer car now with my weekend driver. Low profile design and no obnoxious light to glare at you when you drive. Highly suggest this product. You won't be dissapointed.
