My GPS tattle tale Livorsi will not reset from max MPH any ideas or has anyone ever run across this exact issue? The speedo works fine just that I can not reset the max recall any information would be great.

why would you want too? its the max the boat ever went? Unless you repower with Less. You can use iphone app for max speed. I primary use my GPS speedo just reference, also have chartplotter just below to compare.

Do you have a recall button for top speed? Some do, if so you should be able to clear it.. My gps is a Gaffrig and no button. no clue how it resets but it does tell me the fastest the boat went..

Maybe he left the key on and then hit the Interstate.

Haha i was going to say the same thing!

I would check the connections of the recall wire (I think its the grey wire) and make sure it didn't wiggle loose.
