Okay I found my old original Pioneer 2007 map disc and checked out the files on the disc but not seeing the needed files that DV8er listed in his post above. (see attached images)
Can anyone who has access to these files package them up in a zip file and post it somewhere? I've checked all my newer discs CNDV-90MT and CNDV-100MT and none of them have these files.
My AVIC N4 was working perfectly with the CNDV-90MT disc and started showing the 'Please insert appropriate disc' error after I attempted to upgrade to the CNDV-100MT disc. Has anyone managed to fix this problem t
