avicfix always sells old content.
The newest content is always in asd255786
now it has version 2018Q3, which is not in the Naviextras store
asd255 did a lot for the community.
All his patches are available on the forum for free.
avicfix uses these patches and content from the gpspower website to sell you what is available for free.
Content on the gpspower website also publishes @asd255
avicfix did nothing for the community. I see no reason to let him earn on it
