My 7100NEX's maps are getting a little long in the tooth, with the most recent free upgrade being from 2015. I was looking at options to upgrade and I found the following eBay listing:
http://www.ebay.com/itm/2017-PIONEER-AVIC-7000NEX-7100NEX-8000NEX-8100NEX-GPS-MAP-UPDATE-2017-AVIC-NEX-/302388462340
Is this the cheapest/best way to update the maps at this point? Is there a free option that I am not aware of? Any tips would be much appreciated.
