Hooking up to the reverse switch - Jensen VM9510 Car DVD Player

Did you hook it into the reverse wiring circuit of the car so the unit knows when you select reverse?

There should be no switch to turn off. The back up alarm is hooked directly to the reverse lights ( On most units if equipped ) or the reverse switch. If the unit is equipped with reverse lights,do they work? If not check fuses. If not equipped with reverse lights suspect the back up alarm to be at fault. You can test it with a test light to see if power is being applied to it when in reverse

You may be able to use a power window switch to do that

Check your reverse switch on the transmission to make sure its hook up . You will have to probably replace it . If you have not tried that first . Use a light meter to check the reverse switch if you have power at the plug then its the switch if theres no power then check your fuse box for blowen fuss

YES THERE IS A FUSE, BUT THERE IS ALSO A SWITCH MOUNTED ON THE TRNSMISSION, USUALLY THE WHERE GEAR SHIFTER HOOKS. HAS A SMALL LINKAGE ROD FROM SHIFTER LINKAGE TO SWITCH

if you can not find wire for reverse just hook into backup light wire. I do not know what color wire is for backup lights off hand. but if you put brake on,car in reverse, you can probe the wires to see which is the backup ones. this way you may be able to hook into them under dash or at the mud guard on bottom of the door that covers the wires to the back of vehicle.

possible bad reverse light switch or out of adjustment. located on trans or at point where trans shifter rod or cable hooks to trans.

I have a diagram I made s few months ago for one of my customers. I will sen it on to you later today. It is a bit tricky...Craig

yes

It sounds like you may not have it wired correctly. When the vehicle is reverse the cam works, but when you shift to any other gear IE: park, drive etc you go to black screen as if no signal. I had basically the same problem on my unit, different unit but...on the back of my unit there was a wire, you probably have the same, that said rear cam 12v dc.I assumed this meant any positive wire would do, but this is NOT the case. That wire must be hooked to the 12v positive reverse light. With my cam I had the wires from the cam hooked up, red to positive reverse light wire, black to ground and obviously video wire to the video in on the unit. but the problem arose with that rear cam 12v dc wire on the back of the unit. It NEEDS to be connected to the same 12v dc wire as the cam itself. This acts as a 'switch' when in reverse, IE: the reverse lights come on sending power to the wires to turn on the cam. When you're not in reverse the camera 'switches off' because the lights are not on, thus no power is being sent to the wires, thus returning the unit to its normal operating screen. This worked for me, hope it helps. Good Luck.
