Concerning dvd playback, as long as you go for a touch screen head unit it almost definitely will have a dvd player. Don't think I'd ever watch a dvd in the car but like you said it's just a nice feature to have.
I wasn't fussed about a satnav built in either as I have use a tomtom with lifetime map updates. But saying that, if your phones an iphone you could get a cable for about 20quid and then you could use your phones apps on the headunit including the satnav.
I would of liked a rear usb input, but my head unit was a birthday present from my Missus so I didn't want her spending too much on it. I think it's the pioneer 3400 or summin that has a rear usb. I'm not too fussed about it though as I got myself a sandisk cruzer which is a very tiny usb, it sticks out the head unit front usb socket by maybe 3-4mm, so it's definitely not in the way and you'd never notice it.
Most head units, if they don't come with bluetooth as standard, also have a bluetooth version for around 50quid more. Mines the 1400dvd for example n it doesnt have bluetooth, but then theres the 2400bt which is exactly the same unit but with bluetooth. Like someome else said, look for head units that end in BT
With the camera, most touchscreen head units do come with a camera input, but make sure by reading the specs or contacting the seller.
Vinyl wrappings easy. I used to have all my interior parts carbon wrapped. Just take your time, don't rush and keep the wrap warm and you'll do a nice job. I sinse went down the harder messier stinkier route of hydrodippimg mine instead. Well worth it in the end but hard to get right and wouldn't recommend it as theres a lot of effort involved and easy to get really wrong. Plus it !Removed! stinks horrible due to the chemicals involved.
Concerning car security, when i first started looking at head unitsm which was a long thought out process, i really wanted a detachable faceplate for the security feature, but as you said not many of them have this feature n ones that do are usually expensive.
Thing is, if you remove the face plate it actually makes it more suseptable to thieves. Cause if you remove it, it advertises theres something worth nicking still in the dash and expensive enough that you'd go to the trouble of removing the face plate.
So they'll still smash your window and rip the actual head unit out the dash. Then all they'll do is stroll into halfrauds n lift a faceplate off a display unit.
With having a better alarm, again it probably wont stop em still smashing the window. Whether or not theu got the bottle to still climb in the car n rip the unit out with the alarm going thats another story.
So what i've done is create a fake, factory looking and very convincing faceplate from a stock 6006cd that simply sticks over the front of my head unit so you'd never know it was under there.
