    For street ( or easy ds) riding I use zumo 550 and 78. 78 is loaded with tracks, zumo with routes, plus I can easily deviate from tracks and see big picture on zumo, do easy navigation.

    For tight single track I use 78, zumo in bacpack, just in case.

    I have a Nav IV that I keep mounted all of the time and a 60Cx that I add for backroads. The latest Garmin NTNA is always loaded on the Nav IV. I keep Topo West 24k loaded on the 60Cx for the area I am doing offroad.

    I tried using Topo loaded with NTNA on the Nav IV but it sometimes crashes with both map databases active.

    Does having an iPhone count? If so, I have a GPS, that, and an atlas. Is that three? 2.5? 1.75? :rofl

    First it is possible to have one GPS provide topo, roads, routes, maps and tracks so for the folks that are mixing two because they "work different" perhaps you might learn to work one really well.

    Once this is established the only reason for two is if one breaks in east bumfuck. IMO, the only reason to have two mounted at once is to pose or to prove you need different devices to do the same job differently.

    If you have two identical units with the same datasets and firmware should the one on the mount go tits up you have a spare in your luggage that will work *exactly* the same way the busted unit did.

    Granted you could continue to carry different units; perhaps the true adventurer would then carry a spare of each?

    I definitely like and benefit from two different mapsets, BUT in the IB connotation, I understand, both running the same firmware.and.mapset. You live by the route youve picked, no? In other kinds of rallying or DS riding, like this weekends PDR I would have been screwed without the 60csx running last years maps.

    I have 2, or technically 3.

    Droid as a last resort backup.

    I have been using a Garmin 765T, which has served it's purpose, but is not waterproof, etc.

    Just got a Zumo 665, which will be primary.

    For every day riding, the Zumo will be the work horse, but for rallies, the Zumo will have my route and points to stop at, and will be used to make adjustments on the fly, and the 765 will be used for the route and left that way, so I will know my ending time. I did my first rally a month ago and realized that fiddling with your one gps is not a great plan, especially when time of arrival is so important at the end of the road.

    OK Show me a Garmin that routes on TOPO, May be the new ones will but my 60cs would not.
    That is the reason I dropped Garmin from my GPS usage, too many failures in the past.
    No one Brand does it all, So I look at GPS's that will do what I need, and use them plain and simple.

    Never had my Delorme fail me, so not worried
    Delorme maps are just plain better than anything Garmin has put out for off road use, it is King. My Lowrance is just used for street routing and by no means is it perfect, but in does Topo and NavTec Maps and shows minor roads at much farther Zoom levels than any Garmin so to me it is very valuable when one is out exploring, which is a thing I do once and a while
    I carry a Map and a Compass for back up

    I may not be an expert GPS user but I know how they work and what features are important to me. My Nav IV (aka Zumo 660 + $$$) is perfect for me on the road, IMHO. I have even loaded TOPO 24K West on it and it worked as long as I kept one or the other map databases active and unselected the other. What it does not have is user defineable tracking and track back features which are really important to me off-road.

    My GPSMap 60Cx has those tracking features and I keep TOPO (and only TOPO) on that. Without voice prompts and Bluetooth connectivity (and screen size) the 60Cx is not a very good choice for road use, hence the two GPS's.

    Both my Nav IV and 60Cx navigate fine with TOPO 24K (2010 West). You may be right, the older Garmin's may not??

    Different applications fellas, stay with the tour. In IB situations they must be the same. I think was his point... Do none of you geniuses pay attention to they type of riding he does? Havest thou eyes yet cannot see? :lol3

    I wasnt going to point it out, but you NOT know what apples to oranges means?

    Just sayin.

    Two mounted and one in the pocket ..

    Garmin 60Csx .. because even under the heaviest canopies, lousy weather, and deep ravines the sucker always has a signal .. tiny little screen but the unit can take a butt-kicking and keep on working ..

    Garmin Zumo 855 .. because it does the road nicely with lane assist and it's dirt-cheap when it breaks (and it will, I'm on my second one already) .. once I figure out how to safely and effectively mount up a Magellan Roadmate 1700 the Zumo will be in a dumpster somewhere in some un-named city with no witnesses ..

    .. and an iPhone 4 (no Suri) on Verizon because they usually have a signal when other's fail .. also great for NOAA weather maps .. yelp .. gas buddy .. reaching out to ADV in case of disaster .. etc.

    .. I will be getting a SPOT II very soon as well .. for true emergencies (may I never suffer one) when you need to launch the cavalry and helicopters .. I understand that they can blue-tooth connect to my iPhone too ..


    .. I won't mention I usually also keep paper maps handy as well .. cause sometimes the feces hits the rotating airfoil ..

    Map76 and Zumo550 plus paper maps when "out there". I like the 76 for offroad and the fact that it will load tracks for more precision when needed. But that little screen is gettin' tougher to read every year and the Zumo shines here. I personally find part of the enjoyment planning and getting in/out of being lost.

    I asked about 2 GPSs because of my current long shuttle. I want to let one GPS show its calculated route and have another GPS show an overview so I can better see some of the alternatives in the next 20 to 50 miles. This is mainly because of my dissatisfaction with the routes the the Nuvi calculates on the fly. I frequently ignore its directions and I'd like to have better information for ignoring it.

    The problem is that small GPSs don't show enough area to see the alternatives. (Or when it shows a larger area it doesn't show the detail.) I may look at the 7" Magellan RoadMate 1700. It may be large enough to show a route and some of the other roads in front of me (i.e. one GPS, not two).

    I don't think I've repeated a route in over a dozen round trips to Ohio. My dad is doing better so I may have many more trips in the future. I know I'll go several more times this year.

    THANKS ALL for your input.

    Sadly there is no longer a Garmin made that will be a good replacement for maps. All the new ones suck when it comes to getting road detail on a scale greater than .8 miles.

    The one that will do what you seek is the 276,376 or the 478 all of which have been discontinued.

    My Nav IV (Garmin 660) will go down to 50ft resolution. Yes, the 2006MY Garmin 60Cx I also use will go to 20ft but with a screen about 3X the size on the Nav IV that is pretty much equal. Have you tried turning delcutter off, or going to the highest detail on any of the newer Garmins? With speed controlled auto-zoom I find the newer Garmins much better than the older ones.

    You miss understand, Garmins will not show minor detail at farther zoom levels, not closer, who gives damm about 50ft,
    My Lowrance H20 will display minor road detail at 15 mile zoom, my 60C Garmin,s looses detail @. .5 mile
    When will GPS MFG's use High Resolution Screens and give us Minor Road Detail at 5 miles or more???

    Exactly.

    The biggest sin Garmin is guilty of is adding .JPEG images to the mapsets. This is what made the maps too big to fit in the street pilot series and the fist generation zumos.

    This is part of Garmin's master plan to define "lifetime" as in lifetime updates. Remember when lifetime might mean as long as the purchaser lived or as long as the original purchaser still has the equipment? Well now Garmin like many others defines lifetime as the lifetime of the unit.

    Now here's the problem... Generally speaking halfway well built GPS units don't break and if they do they're pretty easy to fix. We've had a few on the ships and even the yachts that go for years or even a decade with no issue.

    So what's a good corporation to do? Figure out a way to control the lifetime of course. Garmin's answer is to define lifetime as follows (From the terms of use)

    A product’s “useful life” means the period during which the product (a) has sufficient memory capacity and other required technical capabilities to utilize current map data and (b) is capable of operating as intended without major repairs. A product will be deemed to be out of service and its useful life to be ended if no updates have been downloaded for such product for a period of 24 months or more.

    So I'd be willing to wager that every Garmin has an intended lifespan of no more than four years. If you read the rest of the terms if you don't do any updates in 24 months they can declare you unit at the end of life, so some guy that buys a unit at retail, never updates it in 36 months and then calls support with a problem can be told to pound sand.

    Garmin's screens are ok but the bullshit jpeg and other background crap are sucking up all the benefits of newer processors. I expect this will be the trend as it seems Garmin's goal is to have a street view for every intersection in the database for all the on road devices. That should keep the lifetimes down right along with performance.

    Agreed and understood ... at 4mi I loose road detail on the Nav IV and any other GPS I have used by Garmin. I don't ride that fast where it is problem for me :D.

    It is not that we want detail while at speed, no, But when out exploring and you come to an intersection or the proverbial Fork in the road, and you want to see if a road connects or goes through, you zoom out and see the big picture, Right now you have to Scroll and Scroll and it is a pain, why can't we just zoom out like my Lowrance and see minor roads at 15 mile zoom??
    My Delorme will display my custom map files at very long zooms which is a good step but you loose minor road detail at .5 mile on the standard Topo maps.

    Precisely! And when I zoom out and scroll, the GPS often interprets scroll motions as select taps so more of the map is hidden behind an identification balloon for "Coordinates" and buttons for "Save", "GO", and "Set Location".

    When I zoom out to show enough area the GPS shows me in the middle of a sea of white -- it's as good as not having GPS at all. These are often roads that are not on full-state roadmaps. If I was willing to carry 8 or 10 Delorme atlases on a single trip I'd either be on the wrong page too often or spend half the day stopping to turn pages. (Not to mention that neither tankbag will show half a Delorme page.)

    Dual GPSs may fix part of the problem from paragraph one, but none of the compact ones will fix what's in paragraph two.

    I've seen two other ADV mentions of the Magellan RoadMate 1700 (7" screen) and I'll research it more. With one GPS I'd still want the ability to quickly zoom out and see what's ahead reasonable detail.
