Installed a Garmin 93sv+ and Livescope on my Tracker 190 today,also a double mount and ran new wires back to front. Son did the upgrades and linking for me , what a job I have never done an installation myself it was a learning experience for sure. Gonna go out in the morning and see what all the hoopla is about, sure hope the expense and sweat was worth it.Let you know tomorrow how it works out.
