Garmin ECHOMAP UHD repair?/

[Maggiesmaster]

My EchomapUHD 93SV won’t turn on. Garmin support said if it’s out of warranty  they’ll exchange it with a refurbished unit for $250. The refurb. unit only has a 90 day warranty. But they don’t do repairs. Does anyone repair these units?

You may want to shoot @12poundbass a message. He’s pretty up to date on Garmin.

Thanks @GaryH for the nod of confidence but I’m not that up to date or knowledgeable enough to help out. 
 

Silly question but have you made sure you have power to the unit?

 

@Todd Driscoll is an actual Garmin pro maybe he’ll swing by and try and help.

It certainly could be the head unit that is faulty, but more often this issue is related to power supply (power cable, connections, fuse, or cradle).  If you have access to another unit, try it in your current cradle to help troubleshoot your issue.

I don’t have another unit, but I checked the voltage across the outside cradle pins & it read 12.8 volts.  Both the cradle and unit pins look ok. I sprayed them with electronic cleaner, and that didn’t help. I’m going to try on the lake again this afternoon to see if that’s the problem.

Update: cleaned all the connections with electronic cleaner and cleaned the carriage holes with small craft wire.  Went on the lake yesterday for a trial. Ran good for about 5 minutes, then went blank. Restarted ok, and it ran for almost one additional hr. without turning off. Going out tomorrow morning for another trial.

Went out this morning and the Garmin wouldn’t turn on! Checked the power to the cradle & didn’t have any. Searched the power cord & found a really loose connection where the boat wire connected to the power cord. Cleaned the wires, applied dielectric grease on the connector & retightened.  Everything ran fine for the rest of the morning. Looks like Todd was correct; thanks! Hope this solves the problem.
