This may be a stupid Garmin 742xs Navionics question

[watdog]

I am going to buy a chartplotter and narrowed it down to Raymarine Axiom 7" or a Garmin 742xs both with Navionics. What makes it confusing for me is if you buy them with "Navionics charts" does that also include dock to dock routing? Raymarine is clear that it does but Garmin who owns Navionics is not so clear. To me, this is a huge selling point and it is very downplayed on Garmin units. Maybe when Navionics is installed it always includes this feature, but to me, it is not clear. Thanks for any help.

So i had the same question and in Garmin they call it Auto Guidance, I have the 93sv.

Excerpt.
"You can use Auto Guidance to plot the best path to your destination. Auto Guidance uses your chartplotter to scan chart data, such as water depth and known obstacles, to calculate a suggested path. You can adjust the path during navigation. "

Like you I wondered why it wasn't more prominent since they did by Navionics.

Go Online to Garmin. Go to support and check out the Manual. That is what I did. Search term "Auto Guidance". Of course I haven't used it yet and I have no common frame of reference to compare it to.

Thanks, the terminology of "dock to dock" and "auto guidance" threw me off. For the life of me, I can't understand why this is not a top selling point. I live in an area on the Chesapeake Bay that has serious shallows to avoid and I have been using a tablet but want something permanent. Thanks again for the reply, and I am probably going Garmin.

Cool. I am going with the 9" one, not much more and it will be better for split screen, plus easier to read.

What is your plan on mounting it?

That's pretty much what I was thinking and I already have the RAM ball mounted for the tiny GPS I have now. Do you think you have room for a 9"? I think we have the same helm and I am worried I couldn't squeeze a 9" in there. I do really want one because I have to use reading glasses, but not while on the water.

 

[HangOutdoors]

I believe so, i wear reading glasses as well so that is why i went for the nine inch screen

 

[watdog]

I have searched and can't find the actual dimensions of this or any other unit. They all say 7" screen or 9" but no overall dimensions. I want it as big as I can fit so I can see it. If you buy yours first please post pics.

not a problem, hopefully, my stupid question can help someone.

So I went with the Garmin 74CV because I don't care about side-scan sonar and I could see the 7" without reading glasses. . Got it installed today and I am still questioning "auto routing". It did not offer me the option when I tried it, but I was on land so maybe it will be an option on the water. Then in the manual, it states "Auto guidance is available with premium charts, in some areas". I hope I don't regret buying a Garmin.

 

[HangOutdoors]

I can't confirm yet since Mine is not installed.

 

[watdog]

Finally found my answer. My unit does NOT have auto-guidance, even though it is listed in the manual and specifications. Yours will have it. You can go to Using Auto Guidance on a Marine Chartplotter | ECHOMAP™ UHD 74cv | Garmin Support and click chartplotters that include auto-guidance and it list the units that have it. I would have to buy another map. Returning this to Bass Pro tomorrow.

If you have the 93SV you are in the same "boat" as me, no Auto Guidance and will have to buy more maps $$$$

 

[HangOutdoors]

Do you have the LakeVu G2 or G3?

 

[watdog]

It has bluechart g3 which has auto-routing built in but in the 74CV it is a locked feature until you buy another map. Not happy with Garmin right now.

So even though I am irritated with Garmin I returned the 74SV and bought the Garmin 742xs. It does have auto-routing out of the box, but it is not as good as Navionics routing and not as nice of a unit as the 74SV.

I did learn that if the second digit of the Garmin model number is a 3 it's for lakes and if it's a 4 it's for the coast and adds about $100.

First number is screen size - 7” / 9”
Next 3 - inland or 4 coastal
