J07,
What antenna did you buy and from where? I just did the same thing for my '08. Easy drop in replacement. I am seeing everything you and others have mentioned....no NAV, can't set clock or calendar. In fact, my calendar stops at 2014.
Does the NAV antenna plug into the small red plug (looks like 3mm) on the rear?
Thanks for any help!
Yes it’s the pink plug, I got rid of my Nav unit after my red expy got totaled because it constantly lost signal and despite several antenna changes it never helped. I got 2 off eBay and one from Ford, none worked well. I’m assuming the unit was going bad as it kept getting worse with time. The antenna is a magnet and you put it right under the dashboard on top of that metal. Any brand should do. Good luck and hopefully you don’t have bad luck with it like I did. I think I’m the only person who’s had one go bad lol.
