Updated firmware & basemap software per instruction on HB website. Process went as described but now having issues with depth, DI and Sonar. Depth correct, disapears or det to max depth at 2400 feet and reads between 1400-1900. feet, , partial sonar display or none. DI display blank.or thin DI line at top because it's stuck on 2400 feet depth mode. Depth is set on auto Please see pics. Any help would be greatly appreciated.

Restore Defaults and set Max Depth to about 10' more than the deepest water you navigate on.

Thank you Wayne. Did that earlier, did not resolve issues. Called Hummingbird support first thing this morning and did that again as part of the troubleshooting with tech and no resolution. They recommended connecting to another transducer to see if my unit responds better. They were very helpful trying multiple settings but could not resolve issue. Now I also do not register voltage reading. They think it may be the transducer. It was working fine before the update, so I'm a little skeptical that it is.

Having same exact issue but just with my bow unit. Console unit is working fine.

Having same issue with a Helix 12 Chirp Mega SI G2N GPS unit at console. Affecting sonar, SI and DI. Transducer is on the bottom of my jackplate. Seemed to work fine on Version 2.180.
