Guys,
My MKX 2011 will be 1 year old this month, and first when I bought this I also tried to use the access point with no success. I went through the same problems, for instance the access point will tell the password used is wrong. I was trying to connect to my home access point to see if it will work, but the sad thing is ford told me there is no USB stick in Canada that is supported at the moment. The only way it works is if you use bluetooth, but believe me this feature is useless since you can create a hotspot with your Iphone or Android.
