Default Garmin bluechart newbie ?

New to me boat came with an older and a newer Garmin.
I bought a chip off craiglist for the cica 2000 Garmin

question is about the 74SV

I bought what i think is the fanciest chip off ebay for the 74sv- bluechart G2 vision hd
?

what can i do with this chip? Geek me up. Can i plan routes? I dont need to do that just thinking of something different to so rainy day at work.

What do i need to read and write to chip between office and boat?

question 2:
how hard is it to add radar? do i simply buy a garmin dome?
follow up: what really is the difference in the HD (the cheapest one i would get) and then fantom? HD+

You have to be careful on Ebay maps. Make sure to plug it in and see what vs you have. Many claim hd and are actually 3 to 5 year old cards. You can see what you have by down loading homeport on your comp and seeing what it says. You can also stick in machine and when it boots up it will tell you what you have.
On homeport you can plan trips and make waypoints etc.
The g2vision and hd cards offer a lot in the way of navigation and detail. It would take pages to fill it all in here. Best thing to do is play with the options.

thanks

follow up?:

i believe the "newer" Garmin 74sv is NOT nema 2000. correct?

bit of a bummer. What auto pilot will work with the older 0183 network? I watch a youtube video that when paired with a compatible autopilot the boat will follow the autopath created by gps between waypoints.

thx

I have the 74sv. You can download Homeport from Garmin's website if you want to plan routes.

Without a map installed on the laptop in homeport it is pretty useless.

manually entering a waypoint from google earth is way off on the base homeport program

Pretty sure you won't be able to use radar w/the 74sv. It will have to be a stand-alone system w/its own screen.

i am hearing that my "newer" 74sv isn't all that.

Guess i would be better off to save some money for a nema2000 touch screen and plug the transducer into that and then add auto pilot and radar...

hey, its only $

It works for me. Copy the base map from your unit to the SD card.

Its a good unit just a little limited on the add ons. The next step up is big and so is the cost. Look at a 1040xs as well.

Yeah, im finding that out

In my experience, I have done very well with learning the older sonars that come with the used boats i Buy.
For example when I owned a 1999 COntender it came with all circa 2000 radar and sonar. None of it was networked of course but I learned how to tune them and I could find birds, shadow charter boats offshore and tell what type fish was under me.

Its just that there is so much cool tech now. AIS, gps overlays, route following autopilots

So I am guessing that I will learn the 74sv sonar and sideview and look to add a second screen that can be networked and add all the cool new AIS, digital radar, etc

sigh... $$$$
