I recently purchased a 2013 MKS which is equipped with the navigation and blue tooth.
I have had a problem with the navigation resulting in freezing in the middle of directions and/or not able to get directions.
I was told by Lincoln that there is a glitch with the software of the Iphone and the Lincoln Sync system.
They are aware of the problem and hope to solve it by the end of the summer.
I have had the Lincoln in the past with navigation and never had a problem.
This new system is not working well at all.
Lincoln needs to improve Sync system with iphone users
I also have 2013 mks, I have had trouble with the nav, computers, air conditioning, voice command and bluetooth. I have a samsung telephone and it's not compatible with the usb port. The service manager told me microsoft and apple products have problems, if lincoln doesn't work with apple or samsung, whats left. I keep on complaining, but they don't seem to care.
