OK, I've had the Garmin GPSMAP 60CSx for four days now. I spent a few days learning about it and then a few out and about with it. Wow, this thing is really really nice! I made the right purchase with this one.
Before I say more, let me say that the specs on the Magellan Crossover finally came out ... and it does NOT have UTM coordinates. Bad move on their part.
The GPSMAP 60CSx setup for road-use runs about the same price overall as the auto GPSs. It only costs about $370 for the GPS, but add $170 for the detailed maps, $25 for the RAM mount, and $10 for a case (I like the simple $10 nylon case better than the $15 see-thru case), and $18 for the 12V auto power cord, and you've spent almost $600. The Magellan Crossover comes with all that stuff and costs about $550.
For use on a trail, the GPSMAP 60CSx is easily on par with the best of mapping GPS's. The Sirf chipset does lock on fast and I've actually gotten a full 3D lock well inside my house with shutters on the windows closed. Amazing!
Garmin sells 100K maps for the entire U.S. and 24K maps for many of the national parks. I bought the pre-loaded City Navigator North America MicroSD card - it provides detailed maps and full routing capabilities.
I'll admit that I was a bit nervous that I'd purchased a great trail GPS but a mediocre road GPS. I'm glad to say it is a GREAT road GPS.
I bought a 12V power cord to power the GPS in my truck and a RAM mount to hold it. When plugged in the backlight stays on and the unit's bright clean screen is very easy to see even with my older eyes. On the way home I accidentally hit the GPS pretty hard with my hand, and it didn't budge a bit. Very secure.
The screen on the GPSMAP 60CSx is almost half the width of the Magellan Crossover (2.2"x1.5" vs. 2.1"x2.8"), but when routing it doesn't really matter as the smaller screen displays everything needed just fine. Ironically the larger screen can't show as much since it is a touchscreen, which means the buttons need to be quite large for fat fingers.
The GPSMAP 60CSx treats all points of interest (POIs) as waypoints. Hit the Find button and you get a menu of icons providing a whole bunch of different "Find" tools to help search for waypoints/POIs. You can search for Waypoints (that I've saved), Geocache waypoints, Cities, Exits, Recent Finds, Addresses, Intersections (ID city, then name two streets), Food, Fuel Service, Lodging, Shopping, Bank & ATM, Entertainment, Recreation, Attractions, Community, Hospitals, Transportation, Auto Service, and Others. The first day I searched for my home and office by entering the addresses using a fairly decent on-screen alphabet pad - it quickly found them - and I searched in Recreation for the county park where my son was supposed to have his Scout Klondike Derby (it got cancelled due to -10 windchill). I saved them as a Waypoints.
This morning I plugged in the GPS in my truck, placed it in the RAM mount - a very solid mount! After turning on the GPS, and getting a very fast lock, I hit the Find button, then the scrolled and pressed the Enter button for the Waypoints icon, and then scrolled and pressed the Enter button for the waypoint named "Office". I pressed Enter to select the Go To option. I pressed Enter to select the "Follow Road" option (this does the road-routing - the other option is "Off Road" for trail use). The GPS took maybe 7 seconds to calculate the 14 mile route.
It shows the route on the map and has a special route turns page that shows each planned turn and the total route distance/time. At the top of the map page it shows the first instrucitons "East to Jones Rd". When about 500 ft from the intersection it displays a zoomed in display of the turn with a large arrow over the roadway indicating the direction of the turn and at the top "Turn right on Jones Rd". It also counts down the distance and time to the turn. Later I found out that it displays a pre-warning and beeps once about 1/2 mile from the turn and then displays another the turn screen with text on a red background and a double-beep about 500 feet from the turn.
I should mention that the route it gave is indeed the shortest, nicest route to my office, but I know that there is too much traffic on the way, so at one point I turned north when it told me to turn south. After a few hundred feet it recognized I was off-route, took a few (5?) seconds to recalculate the route, and then gave me instructions for the new route.
In between turns it shows the route in "fullscreen", to let you know where you are on that leg. It is easy enough to zoom in or out as desired.
At one point the map didn't know about a recently reconfigured intersection. While traveling through that intersection the GPS thought I had overrun it, gave me a new route, then hesitated a bit, but soon recalculated my route again and I was on my way. Very nice.
The Garmin GPSMAP 60CSx is a great GPS and well worth the price.
The short of it is that you can spend $550 on a Magellan Crossover and get a good road GPS that has some features of a mediocre trail GPS, or you can spend $600 on a Garmin GPSMAP 60CSx and get a great trail GPS and a great road GPS.
