Jensen flip out head unit volume knob doesn't work . the remote works fine but just that one problem.. and i cant seem to get the DVD to play.! ( bought it used..)

CAN YOU USE CEMENT TO ATTACH IT TO THE ROD?

If this is a combo unit (TV with DVD built in) you need the original remote---Universals almost always are missing key features the original remote had as most companies have someone else make the unit and put their name on it.

If you need to remove the head unit, have a look at the removal guides at www.carheadunit.co.uk

i had quality auto sound install it for me, and they added a pulse switch. my dvd works while i drive the car.

all youneed todo is take ur pink wire from headunit and connect it with the ground wire and there ugo

There isn't any code that I know of. Most DVD head units have one extra wire in their wiring harnesses, compared to a standard CD head unit. On mine, it's a peach-colored wire, and is the activation wire for the DVD feature. During the installation, the instructions call for this wire to be tapped into the emergency brake indicator light wire. The reason is this:

The e-brake indicator light is what is called a "ground complete" circuit. That means that the bulb always has power applied, but when you pull the brake, that puts a ground to the wire and completes the circuit, allowing it to illuminate. The head unit sees this ground, and activates the DVD player.

In my Jensen unit, I simply ran this wire to a ground (I used a screw near the fuse box), and I put a switch on the wire, so I could break the ground contact at will. Jensen calls for a procedure to activate DVD playback. In their instructions, they tell you to select DVD from the option menu, and when the "lawyer screen" comes up (the one warning you to park before you watch a movie), you release the e-brake for 3-5 seconds, and then reapply it. To simulate that with the switch I used, I leave the switch closed (activated), and select DVD. Then I flip the switch "off" for 3-5 seconds, and flip it back "on". This tricks the head unit into thinking I put the e-brake off for a few seconds and then put it back on, and the movie will start. Then I can drive away.

Basically, ground the wire that is used for DVD activation, and put a switch inline on it. Then you can break and reapply the ground in whatever manner is required by the manufacturer of your head unit. If there is no off/on sequence with yours, as there is with mine, simply ground the wire to a screw inside the dashboard and you're done.

I just hooked the pink wire directly to the same ground spot as the head unit and it works fine

I have the same unit, your unit sounds like its defected. Mine on the other hand has a static noise coming from its speakers, does yours do that too?

I had this problem and pressed all the keys until I hit the SYSTEM button on the remote control. All was fixed.

I have the same problem! tuner works just fine. I cant access the dvd mode. i can only access tuner, video input, and rear cam. Ive tried different cds and dvds and it did not help. Also it seems like the ejection mechenism is running continuesly.
