Nice fish. Really no idea when Garmin plans to release a new update.
Believe you me I was not confident in doing the rollback. Like you I could still use my unit but grew very frustrated with all the clutter and dead zones making it difficult to see my bait and fish. I was pretty puckered up doing the forced update. It took less than 10 minutes from beginning to end but I was really nervous until my unit rebooted and I seen everything worked. Roll back image is better, not perfect but don't think it ever was but it is a big improvement over the last 2 Garmin updates.
