Anyways, All of the electronics are ancient. I am looking to install all new stuff.
My 2 questions are 1) What is a user friendly brand/suite that you guys can suggest, and 2) How often do these types of electronics usually last?
1) There's a lot to be said for using the boat for a year or so before deciding what you really want/need/would like to have. We always like to have a few basics -- depth sounder, VHF -- working, but if some of the other stuff still at least works... you can maybe put off all the bells whistles and hooters that might be available from a new system...
Maybe if necessary augment with a tablet nav app...
2) There's also a lot to be said for an integrated system... but then knowing what individual components you need/want/would like helps inform how a system should be integrated, which systems could make integration easier, etc. Which leads back to 1, above.
3) You might find you need to spend money earlier on minor details... like keeping the new boat floating, engine(s) running, etc.
Anyway, that also leads back to 1, above. Fix critical components first, fix or upgrade other important components next, etc... get around to nifty new electronics when you begin to recover from all that.
Can't speak to many brands, only have hands-on experience with a few. We like and use Furuno systems, but some folks say they'e not particularly user friendly. Many people say Garmin stuff is user friendly, but in my brief encounters their stuff has seemed no more intuitive (or not) than our Furuno suite. (Then again, I'm about as intuitive as a rock, so it almost never occurs to me to start with a new product without having already read the manual. Several times.)
In either (or any) case, usually as any system becomes more capable, it also becomes more complex... so knowing how to use a more-complex system often requires more learning and practice. And of course reading the manual is often a good exercise. And in the case of navigation, it helps to understand how navigation works (what is set and drift, why are they important, etc.), and why, without regard to electronics.
Furuno supports stuff forever (see the recent thread on their radars), whereas Garmin is said to support stuff for about a month. (OK, maybe longer than that; read some threads about Garmin.) Our 10 year old Furuno suite is still working fine and still supported by Furuno. I don't have any ownership experience with Garmin, so can't say. We've also had a few Raymarine components on an earlier boat. They worked well enough; we didn't have that boat long enough to know about long-term support. No experience with other brands.
