when you open it up you'll see a folder called "Garmin", inside that folder should be a folder called "GPX". Drop the files in there and you should be set. If either of those folders don't exist (if you have a memory card in the unit you'll need to create them in that order. \garmin\GPX) just create them. Also for this unit make sure your GPX file has 500 cache locations or less. There were problems in some units if they were added in sizes larger than that. Also make sure the file is less than 5mb in size as this has caused some lockup issues on the oregon units. easiest way to drop the size is to include less logs. hope this helps.

I answered your questions above on the garmin products as those are the units I'm familiar with and could provide quick answers.

This is a common problem. First make sure you have the firmware to the latest version. This can be found on lowrances website. Second, place all your data on a microSD card which fits in the slot next to the usb plug. I returned my lowrance endura out & back promptly after the first week of using it. Had the information wipe on my twice in one day. Moved everything to a micro SD card and problem solved. After other issues with the device I moved to a Garmin Oregon 400t. It's more expensive but was well worth it. Hope this helps.

Someone correct me if I'm wrong, but there doesn't seem to be much difference in the Oregon units except the maps they come with. Although the units ending in 50 (450,550) seem to have a 3 axis electronic compass that will allow you to use the built in compass while the unit is tilted. I've been using an Oregon 400t for the last couple weeks and love it. It's accurate, simple, and the paperless function is great. I pick an area, build a pocket gpx query (premium membership to geocaching.com required) and drop it into the gpx folder on my gps (plugs in via usb). All I do then is load the geocaching profile (tells the gps that you are walking, not to stick to roads, and to use the built in compass), pick a cache near me, and start walking. When I'm close, it beeps and I start looking. Even has descriptions, hints, and logging capabilities. I am going to wait one more week before writing up the review. I currently use my Google Nexus One with [reference to unauthorized application removed by moderator] just to check accuracy and it's spot on every time. Having the maps is nice because you can look at an area you are going to and see all the caches on the map (providing you loaded the gpx files ahead of time). For those people who say it needs a better screen, after some of the units I've tested, I simply turn the back-light off and use the sun for light. Works great. Also, the 400t comes with a great clip to attach it to a belt, backpack, or anything else you can get the metal clip around. As for as sturdiness, you could injure someone with this thing. The unit is rubber covering metal so it's solid.
