Hello All, I am new here and looking for some feedback, I recently had a Ford 2000 explorer finally kicked the bucket with 247K on it. I just purchased a 2010 Explorer EB edition with Nav system which I never had before. Owned by old couple has 39K miles on it. The husband passed away, and I recently just purchased this and little confused with the Nav system . Does this require a subscription? I noticed everything works , connecting my phone, even the sirius radio works , Seems the navigation works but not sure if it needs updating(maps) and if that cost money. But if the whole system needs a subscription including the sirius I am wondering if its working because he had paid for the subscription not sure how long any of this will work up until. If I went on Syncmyride and put vin in to register with my info would it kill everything that is currently working?
