I am also interested in this.
I purchased the housing for the DWW-7VGA in dash monitor from digitalww (just the housing, NO panel) and installed my xenarc VGA in it and added a touchscreen kit to it. It all works beautiful, which is great, but like vwaddict, I cannot figure out how to route the power + thick signal cable and make the monitor push all the way in the indash housing. Infact I nicked some of the insulation off the signal cable trying to close it... it apperiantly got caught in the internal latch.
If I can't get this to work right, I may just take it all apart, take a loss selling it, and eventually buy a fully assembled one from Armen. I hope I don't have to... since I have everything I need already.
I am open for any suggestions and advice.
