Lexus Dash Cam is Plug & Play. Connects to power in rearveiw mirror assembly. No running wires or worring about finding power connections. With a 128 GB micro USB card I have no issues with the OEM Lexus Dash Cam.
Lexus offers two (2) different units. One is an integrated DashCam front facing only. The second is a 360 degree CARMATE DC4000 the part is about $500 plus another 3 hours of labor. I purchased the simple Lexus forward facing camera. I don’t keep cars long enough to justify the extra cost. See attached 360 option. Good luck
