Issues with 2011 MKX MyTouch/Sync System...
Had the vehicle for just over 2 weeks and I am coming up on my 3rd time of having to pull fuse 29 to "reboot" the MyTouch/Sync Module/System. (Seriously considering wiring up a button or toggle switch to the fuse).
List of issues in order of what I'm seeing to the point of having to pull the fuse.
1. System touch response slows down or gets "sluggish" after a day or 2.
2. Menu's start coming up blank. Mainly the Settings Menu's. Starts with 1 (let's say Sound) showing as blank. Then gets worse to where all Settings Menu's are blank. "Blank" means the area where the sub-menu choices are displays empty, just an empty black no buttons.
3. Sync Services pages display blank.
4. After this the entire system slows to a grinding halt. You touch buttons and get the button press audio tone. But the display does not change. You can still change Entertainment stations and sources via the Wheel controls. But, the main touch screen is useless.
5. "Death Roll". Radio does not turn on, right side wheel controls for Phone, Entertainment, etc. scrolls through the menu's and takes selections. But, nothing happens. No Radio, no back-up camera, no phone (bluetooth link on phone does NOT connect to vehicle), no voice control, no fan/temp/ac control. Main Screen is frozen on Home screen, does not respond (visual or audio prompt) to any touch.
At this point the only way to get the system back is to pull the fuse to reboot. Turning the vehicle off (for any length of time including overnight) and on again does not reset the system.
Tech's at the dealer say they have never seen or heard of this problem before. Leaves me feeling VERY reluctant to even bring it in to them to look at. Since all they do is disconnect the battery or pull the fuse to reboot the system anyway. Then it's working for a few days until the "fun" begins again....
I'm in the process of taking Videos with my cell phone of going through the Menu's and all the issue as they progress to show the dealer/tech's. I'm now in line (probably in 4 to 5 days) of having to do my 4th fuse pull.
