BMW 4 Tech Upgrade
A BMW 4 Tech Upgrade project is always challenging because many of the components have to be special for this car. Here are some pictures of how Boomer Nashua deals with these unique installs, many other cars require special components as well. While upgrading the audio system we also installed a premier K40 radar detection system, some would say it is really a stealth radar system. The completed BMW 4 tech upgrade installation looks and sounds great, all adjusted and tuned for this car and the owners tastes.
