PICTURE INSIDE Hi there... Could be buying a new vehicle soon (Mercedes Traveliner), so I was thinking is it worth getting a Sat Nav, with DVD playback and maybe a TV tuner... I know nothing about it, so i will list my wants...and if theres anything i should look out for when i go looking, lmk. 1 Din Space, as far as im aware, so head unit with motorised screen coming out of it please... 1. Sat Nav (preferably in use, whilst listening to cd or watching dvd) 2. DVD multiregion? Playable of PAL and NTSC discs. 3. MP3 player 4. TV Tuner? 5. Additional Video Out to connect to second screen and 6. A Screen that flips down from the ceiling of the van (add to budget). Are these easy to install? I dont mind seperate box under the seat or in the glove compartment, please note no. 1 point. Let me know your thoughts. Thanks!
