The DVD player is for the DVD-based maps. You can't play vids on it.
The sharkfin needs to have a GPS antenna in it (your probably only has a cell antenna in it, like mine).
There's a lot involved, and I'm just beginning to understand it all. I'll have some more documents later tonight to post, but suffice to say, I'm being ridiculed by the 3 local parts departments I keep calling. One just ended up printing a couple of pages of parts, said "good luck buddy", and went in back where he burst into peals of laughter.
There are 41 different EHUs alone to pick from, and only 1 will work for you.
The DVD player alone is $1,133.00.
I've been thinking about the Tomtom go system after hearning many good reviews about it. But in the end, the fanciest brick stuck the dash is still a brick stuck to the dash. it's the same as the best high-quality wired FM modulator being never better than aux-in.
I did a price list some time ago & it ended up being ridiculously high, but I will try to figure it out just as a personal challenge. Don't hold your breath though.
MY ideal solution would be to have a Tomtom go in the space for the CD player on a motorized drawer flip-up mount.
