almost 2 years ago I bought Livescope with the 93 sv uhd .. although it works fine < im getting older and eyes are as well .. what 12" screen model would be a good choice to replace it ? BPS has a 12" Echomap 126 SD" chartplotter on sale now for $1599.00 . would this work with what I have (LVS10) ? would it be a simple plug and play with my existing wiring ?
