Thanks Chris, it’s just darker on the left side compared to the right. I have had the unit for over two years and had been working fine, it is NOT a touch screen. The lower unit is not an issue, seems to of happened after installing a Navionics Platinum map up grade. It’s not blacked, out just a lot darker compared to right side.

No plenty of clearance to lower unit, have had structure scan for rover a year with no problems but did do a Navonics Platinum upgrade about 6 months ago.
