I was near the Tesla service center today, so I decided to stop in and ask a few questions. One of which was about installation of a Dashcam. His comment was that tesla won't install any aftermarket changes and would suggest against getting a cam that requires cutting into the cars electrical wires (or running them through he headliner for that matter) He noted seeing several cars with electrical issues later on from the cams. Does anyone have an alternative that still looks good? Or know if the service center is just over exaggerating? thanks! Taking delivery in sept and getting my ducks in a row.
