For anyone who uses the cheap Chinese sat navs such as Xgody, Nozatec instead of expensive mainstreams such as Garmin and Tom Tom, you may be wondering like most of the universe where to get updates for these things! Well the answer is - I don’t know! However, on Facebook there is a private group that does know - phew!
The group is called the 'Nozatec Truck Sat Nav Users UK' If you join this group, the admins provide Google Drive links to the latest maps, POIs etc (each quarter) to suit Nozatec and Xgody type sat navs running the required IGO mapping software. They also provide instructions how to upload and install these.

There you go - Q1 2018 Here maps personally uploaded for France next month!!

Ps these sat navs are usually sold on Ebay and advertised as having 'Free lifetime updates'. The sellers/manufacturers will provide them for free - but only after you send a dozen emails and essentially beg them!

Not needed by me but thanks for posting this useful information fishcultureman, helpful to others I'm sure :)
