Best customer service I've ever experienced. The customer service and the product are great. Bought this for my son's M4. The USPS lost it in the mail and provided a ridiculous signature. It was a Christmas present and BimmerTech sent another unit, overnight delivery. Then when my son was installing it, he ran into some vehicle specific questions and we received very quick responses from technical service on Saturday afternoon and Sunday morning. The product works perfectly. I highly recommend BimmerTech. Frank, in Austin, TX

BMW M440i audio upgrade I dealt with CJ and Nelson, who both gave excellent customer service. The Alpha One speakers and amp are a huge improvement in sound and I would recommend the upgrade without hesitation. Thanks guys; a job well done!

This review is overdue This review is overdue, but I needed to test the product for a while first! When I first contacted Bimmertech to upgrade my BMW 3 Series E93 convertible, I spoke with Jorge. He was fantastic to work with, and he comforted me before my purchase and later at the shop, ensuring that my car would be in good hands while I waited at a hotel nearby, which he also recommended. My car was retrofitted with Speakers (all), Amp, CarPlay MMI PRO and backup camera, and a code, all purchased with Bimmertech and installed on the same day. It is a two-hour drive, and I dropped off my car a day before. I made another appointment to return to Bimmertech a week after the installation because the HDMI cable was not exposed for me to plug in the Roku for passenger viewing. After minor clarification, Jorge had the technician do this little fix. Overall, it was a pleasant experience, and even my little Yorkies waited with me at the shop while the techs exposed the cable. It was a well-worth two-hour drive, and enjoyed Orlando. The appearance of the interior of my car has not changed visually, but the sound has improved exponentially! It is good that Bimmertech customized the equipment to the acoustics of my car, and it is a pleasant experience to enjoy good tunes at its optimal volume and sound level without distortions. Jorge asked my permission to post my car installation on YouTube. It is neat to see her there. Thank you Jorge!

Carplay MMI Prime I bought Carplay MMI Prime. It was a simple installation and my car feels like new. I can't describe how fast my phone connects to carplay over wifi, definitely faster than embedded carplays that comes with the car. You should definitely try

2019 BMW X3 Apple Carplay install My 2019 BMW X3 came without access to Apple Carplay. I purchased the antenna, OBD connector, and coding session from Bimmer-Tech. The installation went perfect and works just as advertised. The videos provided gave me all the information needed. My wife is thrilled with it! I’m completely satisfied. You saved me a car trade. 🤣🤣
