So, the 8T4T-18K931 would definitely work w/Sync? I found an entry on eBay which is titled: NEW FORD EDGE MKX NAVIGATION KIT 07 08 NAV. It lists Bluetooth, satellite, back up camera, ipod integration, hd capability and video capability. It shows a video of the nav radio after a video interface installation. I'm entirely skeptical but at the same time this would do everything I'm looking for IF Sync would still work w/it.
I've got an '08 Limited w/Sync installed but now I'm wishing that I'd gotten the touch screen interface. I've been looking heavily at the Avic-Z2 but am reluctant to get it because of all of the issues listed w/the steering wheel controls. At the same time, I really like the unit and would forego Sync if I knew it would integrate w/out issues. What I'd really like is a factory nav that would work w/Sync and also plays DVDs with a video out to connect to headrest monitors. (My kids are too young to read to put in a DVD and use a remote to navigate the menu to play the disk w/the headrests w/built-in DVDs.)
I think I've read every post in this forum about the Z2/D3 and the lack of support for video and/or getting an OEM to work after the fact w/Sync but I'm still waffling. If anyone can shed any light either way I'd be very grateful! Thanks.
