Al & Ed’s Autosound improved the cabin tech in a Tesla Roadster.Al & Ed’s got around all of this with a clever solution.The entire audio system is powered by its own Stinger (made by Odyssey) battery with its own charging system.

The factory head unit was replaced with a Kenwood KVT514 motorized monitor with the Garmin-based Kenwood navigation system. They also added a Kenwood Bluetooth hands-free system, an XM Radio tuner, and a cable to plug in the client’s iPod. The head unit’s functions and all of the accessories are all controlled by the Kenwood touch screen, which has a very consumer-friendly GUI.
