I've also heard of a "add on" antenna that can be bought from Amazon for about $30. Not sure where I remember that from, but you might want to do a search related to that. Might be an easier fix.

I found a thread on River Dave about this - fixed my speedo following his thread.

My speedo had the newer external antenna, but it had a lot of trouble maintaining a connection. I found the issue was with the speedo's 12V power output. I ended up wiring mine into my Lowrance GPS. Worked like a charm!

I also saw the thread over on river daves place about the antenna you can get off amazon. Only thing holding me back is tracking down that 3 pin “molex” connector to splice to the antenna also. If anyone knows a part number or what style molex connector that is thatd be awesome. Did some searching with no luck. Hard to tell from the pictures ive seen online if it is in fact the right one

Finally did some testing with this antenna, it works above 30mph speeds, below 30mph not accurate. Reacts very slowly to speed increase/decrease.
