I have an 1198 unit. I'm happy with the unit except for problems I'm experiencing with the view preset keys. When I select one of the presets, the unit apparently thinks I'm depressing the key longer than I actually am. This has the effect of overwriting my desired preset with whatever the last screen was. I've tried modifying my press approach without any success. Initially I thought this problem was specific to the uppermost preset key, but when experimenting my last trip out, found that all the keys will occasionally do it. I was considering doing an upgrade to the latest firmware, but there seems to be a fair amount of negative feedback relative to this version. The unit has a Navionics Hot Maps Platinum East Region SD card installed; I noticed while it was loading the map information, it was much more likely for this problem to surface. However it is still a common occurance at any time during operation. I didn't get any hits when I searched the forum, so I'm wondering if this problem may be unique to my hardware. Anyone else seen this issue? Thoughts?
