Bests & Worsts Reviews from Amazon

So Garmin has on its hands the nearly perfect GPS receiver for me. First let's take a look at the offerings. The 600, 600t, 650, 650t. If it is a 600, then it is without camera. If it is a 650, then it is with a camera. Add the t for included 1:100k topo maps. The pick of the litter is the 650 and here's why: The built in camera allows you to take pictures with an IPX7 waterproofed camera. Keep your phone safe so you can make calls another day. The photos are also Geotagged so you can see where they were taken later. The camera is also very good -- on par with an iPhone. So for $80 more you get a pretty good waterproof camera. But wait -- there's more. It also comes with the rechargeable battery pack so you can charge the unit with the batteries installed and it comes with 3.5GB of storage instead of 300MB. The 6xxt models aren't worth it to me. First the 1:100k map isn't routeable, second it won't work on your computer with basecamp unless your GPS is plugged in to your computer, third for the price you can buy excellent 1:24k maps for your area that are routeable, and have much more detail, and will work with your computer and other devices without installing -- get the DVD. If you don't want the routing and just want 1:100k detail -- then just buy the DVD. There are even free maps available that will get you 1:24k, but they do not have elevation data for 3d view/route profile. I got this to replace my old eTrex venture Cx. It's not even worth comparing them as this is much more readable in sunlight, the touchscreen is as responsive as an iPhone. I use it for mountain biking, road biking, day sailing, and hiking and it works well with just about everything I have. The GPS has been responsive under canopy, but I haven't had a chance to try canyons. I will try to get more data on that with GLONASS enabled as well. Where does it fall short? The basecamp mobile application is pretty weak. I'd like it if it had the full Garmin Connect support that the Edge 510 and 810 have. For example it'd be nice if people could monitor me while I'm out and about and it'd also be nice for my "workouts" to be easily uploaded to connect from my phone. I wish I could send a route to my GPS from my computer and have it download to my GPS via my phone. I didn't have the issues the first reviewer had downloading -- again -- I suggest buying the DVDs as they will work without having the device tethered and they work on multiple devices as well. UPDATE: ANT+ transfer to computer (Garmin ANT Agent) or Android is not supported (same as all other eTrex/Oregon devices). However, USB upload is possible from Android as long as your device supports USB Host and you have the appropriate cable. I used "Uploader for Garmin" from the Play Store.
