Hi All, Just bought a used 2010 FX50S and love everything about it accept the navigation system which is stuck in 2010. I would like to update it to the latest version. I spoke with the Infiniti Dealer I got it from but they were unable to help me. I see on eBay there is a 7.10 version from 2015 but when I look at the details it mentions FX45/35 and up to 2008 years. No mention beyond that. Can someone please point me in the right direction.
