For those who had dealers rig their boat electronics, what should I expect to pay to have my Lowrance units( X-15, LMS 480) replaced with the 93sv UHD + Livescope in a 18' 6" Alumacraft tiller boat? Local dealer only sells Garmin units and they claim to do it everyday but they can't/haven't given me an estimate so I'll ask the "community". With the cost of the units I want a professional to do the work, so I get the best out of them, but I'd like an idea as to the cost. Thanks !!
