Hello I have bought a DVD player radio whatever with a TFT monitor and the description says that you have to clamp a cable to the handbrake that the tft starts. I say I pull the handbrake and monitor goes to so only when I’m standing on n parking space!!! that’s Mist then I can also see at home dvd. you can still clamp the cable where else the tft also runs while driving. n buddy meant that I can clamp on the duration plus but the types can not be used t trust he’s hit his box in Klumb. I don’t just want to see dvd that navi is also running on the monitor. thank you already
