Hi all, My first post after getting my used '07 Edge SEL AWD Plus model. I must say that I LOVE it! Only real concern is the factory nav system is dated when it comes to the display. That being said, it works as intended so long as you don't need to change the destination while driving. My question is, can the Nav system display current speed (as you would get on something like a Garmin or TomTom after-market)? This is extremely helpful as the standard needle display on the speedometer is obviously a little tough to pin-point exact speed. Is this something that would require cracking/ flashing the unit and loading a custom skin? Is that even possible? Thanks all! PS - next posts I'm sure will request info on what programmer to use for improving fuel economy.

I have a 2008 Ford edge with every option except Navigation. All I wanted was a screen so I decided to start looking into it when I came across a nav from a 08 mkx so after talking to the 80 year old man at the ford dealership he said its the same unit the only difference is, is it says thx or lincoln and the colors are different. With that being said I purchased the nav screen and installed it in my edge everything seemed to work until the radio started and then I realized the volume control wouldn't work on the unit itself or on the steering wheel and the sound only was coming out of my front speakers. After trying everything I just gave up and thought it had to do something with the programing part along with my sync stuff. Everything else works though, my navigation, sirius even my music through bluetooth. So I took it to my dealership for programming and the old man told me that he is not authorized to program the radio and he said it sounds like its broke, so I would just have to try to program it myself and see if it works. So my question is this... Is it possible to have this nav programmed to have these items work even my rear sound or does it sound like its a problem with the nav unit? And if it isn't a problem with the unit how can I fix this to work properly? Thanks
