We have just bought some 9" Nextbase Pro DVD players. The bigger screen have a higher resolution and are easier to see. But the 7" should be OK as well.
We had 7" Xtron replacement headrest DVD screens in our last car, which were quite good. They were easy to fit, as you just removed the original front headrests, and popped the replacement headrests in. All the wiring went into the seat void, so no wires were on show. I removed the seat backs, and connected the two seats together, and ran one power wire to the 12v socket in the arm rest. In total, they took less than an hour to install. They took ten minutes to remove when we sold the car.
I planned on getting the newer 9" touch screen Xtrons this time around. However, i soon learned that the Sportage uses "Active" head rests, and shouldn't be removed. I'm not sure if they can even be removed any way, as ours don't come out using the adjuster clamp. (i wanted to see if a warning light came on if removed etc)
Xtron do a headrest post mounting bracket/mount. Although not ideal, it does mean the wiring can be left in place, and the screens slotted in when needed. Two things held me back though. The headrest post bracket is plastic, so i'm not sure what would happen in a crash. Second, there have been reports that the Xtron 905 screens give off FM interference even when the FM transmitter is supposed to be off.
So this lead me to the NEXT BASE screens. They have been around a while, but the problem was still the safety of the mounting system. They have now come out with an extremely safe "Click and Go" system. The headrest mounts have been crash tested, and make fitting simple. The Sportage has odd shaped hearests, so i'm not sure how secure the standard Velcro/straps would fit on. So we ordered the headrest post "Stanchion" fitting kit. These clamp onto the actual headrest posts themselves. All the fittings are steel and have been crash tested. They do leave some wires on show, but once fitted you don't have to touch any wires again. The screens simply click in and out as needed. Our kit came with a handy storage bag to keep the screens safe.
The only downside to these screens is the lack of built in FM transmitter. We prefer to pipe the sound to the cars sound system. That way, we can control the volume level from the front. Next Base do a plug in module, but i'm wondering if it is for sale in the UK as nobody sells them. If not, we plan on getting a normal iPod type FMtransmitter, but that needs either power or batteries etc.
Nextbase do a cheaper "Lite" screen, but these are thicker and don't look as good. If you shop around, you can get the pro screens for less than the "Lite" one...
