C95 update v17 and navionic chart resolution issue

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Jeff,

This is the first such report of the problem described/shown in conjunction with v17.45 and Navionics cartography. We have similarly been unable to reproduce the problem in our offices when looking at the boundary areas. Correspondingly, we have a concern that the problem may be data driven. All Navionics chart cards which are compatible with these MFDs or that have been separately purchased would have been eligible for one free year of Freshest Data updates from Navionics (http://www.navionics.com). Should you not already have done so, then it is recommended that your chart card's contents be updated with Navionics Freshest Data to ensure that it has been updated with the latest available content. Should the problem persist thereafter, then please respond with the coordinates of the problematic location and a photo of the Navionics chart card microSD to SD adapter sleeve in order that we may further attempt to duplicate and correct the problem.
