Question: Is this a 547xs or a 527? "*With the integration of a 10Hz GPS/GLONASS receiver, the 527 refreshes position and heading up to 10 times per second"???
Document: Two of those will wire into your ignition key electrical so when you turn the key the unit powers on and it will power the unit. The other end screws into the GPS unit2. A cable will come out the back and will run to the "backbone". The "backbone" is made up of "T Connectors that run together in a line and looks like a spine. This is where different accessories will plug into.
The GPS unit will have a cable that runs to another T connector in the back bone. The NMEA 2000 will run to the back bone also. The back bone can hold tons of accessories.3. REMEMBER there will be power that runs to the back bone (Yellow cable). This is where it gets confusing. There will be power that runs to the backbone AND there will be power that runs direct to the GPS unit (wired into the keys switch).
outstanding product, I would definitely recommend this products to any one, very easy to handle, easy to understand, and great price
This unit works flawless and with the optional chirp transducer (tm150 m) I can pick up the bottom to depths greater than 2000 ft. It also has great target separation for defining exactly whats under you.
This keeps an even current to the accessories. It basically is a yellow T connector that can go anywhere in the line of T connectors that are connected together. I put mine in the middle.4 If you have questions ask Garmin to send you the full NMEA 2000 connection PDF.. Or here is the link.[... ]It is an awesome display and easy to see maps and overlays. Split screen is awesome.
Purchased for trailered 22 ft cuddy-cabin for trip to Lake Powell Glen Canyon. Base map limited as other reviewers of Garmin marine receivers have pointed out. Bought the high end G2 inland maps to go with it. Unit easy to install with excellent directions. Mapping screen updates so fast I never saw any latency at all. Sonar worked well at all speeds in 200-300 water depths of Lake Powell when Lowrance in dash failed to read past 80 ft and again no latency.
My 84 yr old has done nothing but play with this since Christmas, he owns a few Garmins but this one is the best by far, He takes it on big boat, little boat and airboat, he just loves it!! Not complicated to use. Awesome instrument.
It is a great program and well worth the money! go with the $99.00 transducer for HD. The fish finder is unbelievable. Don't waste the money on $300-500 transducers.This is one of the best units I have used and definitely recommend. Email me with questions. I am happy to offer my 2 cents.
If your going out on the water to due any kind of fishing you need this unit. It will exceed all of your aspects.
Have used it at several other lakes in Southwest with no issues. Recommend highly.
