When I did a refit
, I started with a market survey
of (most/best) reputable installers in our local area.
After winnowing down the list to the three who received the most/best recommendations... I approached each with a list of what I had, what I wanted to save (radar and the DGPS) to integrate into a new system, what I didn't have and wanted to add... hummed a few bars about my own philosophical preferences about hardware
, and networking... and then asked each of them for proposals.
With proposals in hand, and after some discussion with each about potential tweaks, we began homing in on actual installed prices... and I eventually selected the one that seemed to fit my needs (and wallet) best.
The package cost -- which included installation
(which also entailed re-glassing some previous cut-outs, to make the most out of the available real estate) -- was high, but the individual component costs were quite reasonable.
And I'm very pleased with the end result, which is an almost completely integrated system (except for the old radar, which could only be semi-integrated), with multi-function display/chartplotter, AIS, autopilot
, plus redundant GPSs, tri-data transducers/displays, and VHF
If I'd had the time then, I could have acted as "helper" on the project
and so forth), and that would have dramatically reduced labor costs of installation
