I am looking for a 2013 Ford Edge SE and find that there are two types of Edge SE in the same dealer on the internet: one with Equipment Group 101A and the other without the equipment 101 A. The one with the 101 A will cost around $1,000 more than the other. I have no idea what Equipment Group 101A is. The dealer told me it includes: the convenience package, voice-activated sync, and Sirius XM satellite radio, but I still have no idea what are these for. So, is necessary to spend $1,000 on the group 101 A? Thank you very much for helping me.
