BT45-VETTE Bluetooth Music & Phone Interface for GM Class2 Radios with XM (Satellite Radio) Capabilities

I installed it in my 2006 Vette.As someone else mentioned another good option was the Costar / Bluestar to work with the factory Onstar. You CAN stream music from your device to the Costar using it's Bluetooth function, BUT you need an Aux Input on the car's stereo to feed the signal from the Costar into the stereo. The 2005 through 2010 Vette Nav stereos did not have an Aux input. (FYI, some guys change the Nav head unit on the older C6 Vettes to a 2011 to 2013 head unit. This will give you USB ad Aux input but still no Bluetooth or hands free phone features).So this BT45 gave me the handsfree phone option which is impressively good quality. In fact the call quality for both the caller and the receiver is the best of anything aftermarket I’ve used. Close to factory sound quality. Road noise in Vettes is NOT low, and I can be heard at the “other end” clearly!Installation was easy but time consuming. Plug and Play.I installed an Aux input jack and USB charging port also. All of which, including the Bluetooth audio work well too.This won’t give you OEM features of the brand new head head units in today’s vehicles or aftermarket stereos, but if you want to retain your factory head unit as I did, I believe it’s a great option.Someone asked the question about why the console didn't have to come out. Unlike some other units on the market this device does not tie in at the head unit (stereo). It ties in at the XM box. I REALLY liked this idea as I didn't want to disturb the dash area, possibly creating rattles.In a C6 of my vintage the XM unit is behind the drivers seat in the cargo area. The instructions tell you where to locate it.I did, however, remove the console so that I could install a USB / Aux input. I have attached a picture.I am going to get a similar unit by USA Spec for my 2008 F150 also.All in all very pleased.

2006 XLR: Like others wish I had done it long ago. located the mic below the onstar location (see pic) works very well. Took the extra step and cut a slot into the storage box and fed the cables thru it before reinstalling. This will make any adjustments much easier. (See pic) I use this for iPhone navigation, XMRadio, etc and hands free calling (see Video)

The media could not be loaded. Put this in my Cadillac CTS-V, gen 1 LS6. Flawless, works great, had it sitting around and finally summer here to install.Price has gone up but the V's have a crazy radio and hard hole to fill that's looks good. Range is good too. Playing music 10 feet away from the car. Installed under rear seat.Replaced the USA Spec auxiliary audio module that the RCA adapters on it. Same plug so just basically hot swapped them.No complaints.

I had no problem installing this unit in a 2004 Chevy Suburban. It took some time, but was not difficult. The unit plugs into the XM box located just behind the glove compartment door.The one somewhat tricky part was installing the microphone in the original OnStar microphone housing (this is an option only if you don't use OnStar, as described in the answer to one of the questions in the section above). To do this, pop the tiny circular cap off the new mic and push the wire and microphone through. Then, remove the ceiling console (retained by one Phillips screw). Remove and disassemble the original black OnStar mic housing clipped to the side, and remove the old microphone from it by cutting the wire. The new microphone cylinder fits perfectly into the original OnStar mic housing, though the housing does have to be modified slightly with a small razor knife and file in order for the new mic wire to pass through the rear of the housing, and then up and over the top of the ceiling console. From there, the wire was routed above the headliner at the windshield and behind the pillar trim (which snaps off), then down through the dash to the unit.I also ran a 6' lightning cable from the USB port provided in the unit. It was routed through the dash and down under the plastic storage trays in the console (which pop out easily without using tools). I drilled a 1/2" hole in the bottom rear of the center of the hard plastic tray that's nearest the driver's seat. A smaller 1/8" hole was then drilled through the rubber pad in the bottom of this tray to allow the lighting cable end to be pushed through it. This allowed me to plug the phone in right there, where it can rest and charge without any extraneous wiresThe sound quality is excellent in both in hands-free phone and music modes. Though the system is not able to make outgoing calls via a steering wheel button, if you enable the voice prompt as detailed in the instructions, you can dial out verbally by simply using the "Hey Siri" command. The system picks up this command through the mic even with the music playing fairly loud.This was a great purchase and I would highly recommend it.

I bought one of these units and loved it for a few months until it died just past the return time from amazon warranty states one year from date of purchase when I contacted usa spec they tell me the only authorized dealer for them online is crutchfield buyer beware!
