I also will be trying to get it fixed this week, I hope this works then my boat will be 100%!

I cant even get the cover off mine. Do they unscrew or just pop off?

unscrew

I just replaced mine with a Garmin GPS17-HVS antenna.

Red to red

Black & Yellow to Black

White to orange.

No more battery issues in the antenna.

Livorsi and CMI are owned by the same company

I am going to try to replace the batt,still can't gewt the unit apart,will see what happens thnks for all the input

Has anyone tried their's after they installed a new battery. Livorsi said the older ones need to be recalibrated also.
So I brought them my dead one and ponied up for the replacement antenna for my series Speedo.

Next time I just might try that...wiring it to my Garmin output leads.

How do you wire it to your Garmin. My gps speedo is not working either and i was told to send it to livorsi and they'll send it back fixed. I figured I'll leave it dead since I have a very nice Garmin..

Real easy, connect the blue wire from the gps harness to the signal wire on the speedo. Then go into the "Comm" menu on the gps and make sure NMEA output is selected.
