A:AnswerI am unable to confirm, I would check with a Best Buy technician. I do not see why it would not. Best Buy did an incredible installation job and we decided to leave in the factory radio in case we ever sold the car and the install is very impressive
A:AnswerKenwood will always provide harness to connect to radio. you must purchase harness for your car and a possible dash kit. You can call us for more detailed information
A:AnswerThis will stereo will fit most 1 din ( which is the STD car stereo 2"approximate height ) not sure what your Buick is .
This unit comes with a small plug for the back which if you're good with wiring as in determining your vehicles stereo wiring you could make your own harness. If not get the kit ,and face plate might work,but a whole adapter kit is probably available at best buy or on line to ease the installation process.
I am quite satisfied with this unit for it's price.
A:AnswerYes, but you must first make sure the microphone is plugged into the back of the radio. Place the microphone in a place that can easily pick up your voice. It works very well.
