Garmin GPSMap 60C Review

Gpsmap_60c

UPDATE: This model has been discontinued. For more current recommendations, please refer to our handheld GPS buyers guide or our Garmin handheld GPS comparison chart.

The Garmin GPSMap 60C is basically the same unit as the 60CS, minus the barometric altimeter and electronic compass. It has the same bright color screen and can utilize routable maps, so it can do double duty in the backcountry or the car. The 60C, a mid-level model, is a step up from the GPSMap 60, which has less memory and a greyscale screen.

25 readers at Amazon rated the Garmin 60C at 4-1/2 (out of 5) stars. Here’s what other reviewers are saying:

Ski Resort Maps for your Garmin GPS

Many GPS Tracklog readers know that you can make your own maps for your GPS, but we’re just beginning to see entrepreneurs marketing such products. I recently came across Snow Ranger Ski Resort Maps for Garmin receivers, which are available for Colorado, New Mexico and California. The Snow Ranger website provides additional details, including a list of available resorts.

The price is right, at $4.95 per resort, or $29.95 per set, and they can be downloaded online. I was a little surprised though when, browsing the product guide, I discovered that using these maps will overwrite other maps on the unit. This means that you probably need to take your laptop along if you’re using your GPS to navigate to the resort via City Select. This limitation on home-made maps can actually be overcome using techniques described in my book, GPS Mapping. It implements a simple modification of Garmin MapSource, and that may have been a little further than the developers were willing to go!


Garmin nuvi 350 review

Garmin_nuvi_350

UPDATE: Though still available and supported, Garmin has discontinued the nuvi 350. For newer models, check out my Garmin nuvi comparison chart.

The Garmin nuvi 350 has proven to be an incredibly popular touch-screen GPS navigator. Garmin bills the nuvi as a “a Personal Travel Assistant™ that combines a GPS navigator, language translator and travel guide capability, an MP3 player, an audio book player, a currency and measurement converter, a world clock, and a digital photo organizer.” The nuvi has the newest generation of GPS chipsets, the SiRFSTAR III, resulting in fast satellite lock and improved reception. It also speaks street names, so you’ll get “turn left on Highway 128” instead of “turn left in 200 feet.”

What kind of maps can I put on my GPS (and what do you mean by raster and vector)?

I received a PM from the Adirondack Forum today that said:

"…I just bought the Garmin 60CS. I have a question about the maps. Do I need the Garmin Mapsource United States Topo or… the one from National Geographics Topo that I think is better for hiking? If I don’t buy the Garmin Mapsource Topo, can I download maps in my GPS?…"Raster_image

This question comes up so often that I felt obligated to post an answer here. The answer is no, you cannot load National Geographic TOPO! maps onto any GPS. You can however, create waypoints and routes with TOPO!, and transfer these to your GPS, but not the maps. Let’s look at why not, and what kind of maps you can load onto your GPS.

The National Geographic TOPO! maps look just like a paper map from USGS (example above, at right). That’s because they are scanned images, also known as raster imagery. Since they are scans, they have a pretty big file size. That’s why it takes 10 CDs to cover the state of California. And that’s one of the main reasons that GPS manufacturers have taken a different approach.

Garmin StreetPilot 2610 Review

Streetpilot_2610 UPDATE: Most of the several generations old StreetPilot series, including this model, has been discontinued. For a more current recommendation, check out our Auto GPS buyers guide or go straight to our Garmin nuvi comparison chart.   The Garmin StreetPilot 2610 GPS auto navigation system is very similar to the StreetPilot 2620. The key difference is that, with the 2610, you have to load City Select maps to a Compact Flash (CF) card, whereas the 2620 comes with a built-in 2.2 GB hard drive. The next level in this series, the StreetPilot 2650 and 2660 models add a gyroscope which can maintain your position when satellites are lost for brief periods in urban canyons or under heavy canopy. The StreetPilot 2610 is a popular unit. 98 reviewers at Amazon rated it an average 4-1/2 out of 5 stars. Here’s what reviewers elsewhere had to say: read more

Magellan eXplorist 200 Review

Explorist_200UPDATE: The Magellan eXplorist line has been officially discontinued. For an overview of our current recommendations, check out our handheld GPS buyers guide.

The Magellan eXplorist 200 is one of Magellan’s entry level GPS receivers. Unlike the eXplorist 100, this unit includes a base map. Stepping up to the eXplorist 300 gets you an electronic compass and barometric altimeter. Beware however; none of these units can be connected to your PC, meaning all coordinates must be entered manually. A good alternative that comes with a PC cable is the eXplorist 210. And with the 210, you can load DirectRoute maps for highway navigation.

A number of readers have posted Magellan eXplorist 200 reviews at Amazon.

Garmin StreetPilot 2620 Review

Streetpilot_2620

UPDATE: Most of the several generations old StreetPilot series, including this model, has been discontinued. For a more current recommendation, check out our Auto GPS buyers guide or go straight to our Garmin nuvi comparison chart.

 

The Garmin StreetPilot 2620 GPS is a touch screen auto navigation system that comes with Garmin’s City Select software pre-loaded on a 2.2 GB internal hard drive. That’s the key difference between it and the StreetPilot 2610; to get the same detail with the 2610 you have to transfer City Select maps from CDs to a CF card. Going up one more level in this series, the StreetPilot 2650 and 2660 models add a gyroscope which can maintain your position when satellites are lost for brief periods in urban canyons or under heavy canopy. Before moving on to the 2620 reviews, you might want to check out my review of the updated version, the StreetPilot 2720.

58 reviewers at Amazon gave the StreetPilot 2620 an average 4 out of 5 star review.

From the Mailbag

I occassionally get questions directed to my email, so today we inaugurate a new category…from the mailbag. The questions today come to us from Bill Macfarlane, a new geocacher who recently purchased a Magellan eXplorist 500.

"So far I have good luck with it, finding a few caches, but I really think I could be doing more. With this in mind I started to look at Magellan’s other offerings, Mapsend Directroute and Topo 3D, and trying to decide if they were worth the extra. I also have gone through many of the posts on Groundspeak regarding mapping which has added to my confusion…

…While Directroute seems simple enough to understand it usage, the whole sense of 3D mapping and Topo maps in conjunction with the GPSr still seems a mystery to me. Are these programs (Magellan Topo 3D, National Geographic TOPO, OziExplorer…etc) used to help your excursion into the great outdoors? Will they help me find trails that I might not know about in my area or perhaps rank them from a day trip with my Cub Scout group to the extreme hiker? Just where do these programs fit in?"

Read on for my answers…

Garmin StreetPilot i3 Review

Streetpilot_i3

UPDATE: Most of the several generations old StreetPilot series, including this model, has been discontinued. For a more current recommendation, check out our Auto GPS buyers guide or go straight to our Garmin nuvi comparison chart.

The Garmin StreetPilot i3 GPS is a great entry level auto navigation system, that will get you where you’re going without breaking the bank. The mid-level model in the i-series, this unit is a step up from the i2 monochrome edition. Packaged with Garmin’s City Select software, this little dynamo gives voice-prompted turn-by-turn directions, to guide you wherever you want to go. One caveat though — this unit has no touch screen. If you want that feature at a reasonable price, check out the StreetPilot c320.

The StreetPilot i3 garnered 4-1/2 out of 5 stars from 39 readers at Amazon.

Here’s what others are saying about the i3:

Free USGS Topo Maps

UsgsMy recent post about OziExplorer accepting .gpx and .kml file types got me thinking about one of the great benefits of Ozi — it’s ability to utilize free maps. While Ozi isn’t free (though there is a shareware/demo and a trial version that allow you to try out almost all its features), there are lots of sources of free maps to use in it. I’m speaking here of digital raster graphics (DRGs). These are scanned versions of USGS topo maps. They typically come in a .tif format, which can be opened in a basic photo or graphics program. But you need a program like OziExplorer or Fugawi to georeference them. Once you do that, your computer knows the coordinates of every pixel on the screen, and you can transfer GPS data (waypoints, tracks and routes) back and forth between your GPS receiver and PC, layering them on the DRG map.

Here are my favorite sources of free USGS maps:

  • This listing of USGS DRGs has lots of information about various sources of maps, state by state.  Compiled by a frequent contributor to the OziExplorer discussion board, this site has great notes about datums and file formats, designed to assist in importing them into Ozi in an already georeferenced format.
  • From their website, "The purpose of the Libre Map Project is to aggregate and make digital maps and related GIS data available for free."
  • The Mostly Free DRG Reference Page has this to say about it’s name…"Between the various state and other references on this page you should be able to download a DRG for just about anywhere in the country without having to spend a dime (although I have included a few low cost DRG sites)."
  • Of course, you can always go straight to USGS.

There is a chapter in my book, GPS Mapping: Make Your Own Maps on this subject called Maps 201: Downloading Free Maps. It delves into other types of free maps (and aerial photos) and various technical issues that you might run into. There are also full chapters on both OziExplorer and Fugawi.
