We installed a Thinkware F200 Dash Cam on our customer's BMW 3 Series (G20). The camera itself was placed a little off center so there is less exposed wire and will not hinder the driver's field of view. The Thinkware iVolt battery has been placed under the trunk floor next to the car's main battery as there is plenty of room there for storage. As BMW is notorious about battery discharge warnings, we usually recommend battery packs to prevent this and it serves as a benefit to the user for longer parking mode.
