at 100,000 miles the radio turned off and never worked I had the touch screen voice navigation thx sound system, I took it to a radio shop for them to look at it and they gave me estimate of 800.00 plus shipping to get it fix. I knida came lucky I looked online and found one for 180.00 that's better than paying 800.00 to fix it. also another thing the 6 cd changer are known to go out on all the mkz fusion and Mazda
