Too Many Tracks - Montana 650t

Former Member over 9 years ago

I'm trying to feed my new Montana a lot of data that I have built up over the course of a few years in my Delorme PN60 and Delorme TOPO 9. For instance I have a master file that has 218 "tracks" in it. Some of these are just little pieces, but apparently I'm not going to be able to display all of these in the Montana because it will only register 200 tracks? So then I tried a new tactic, loading all of the original tracks in to the Montana. This would have worked, since there are about 60 of them, but as I got halfway through making them show on the map, the Montana told me track memory was full.

Any ideas how I can get all of my tracks to show up simultaneously like they do on my Delorme? Would adding an SD card to the Montana help?

A couple of ways:

It looks like you have two separate problems: too many tracks and too many track points in an individual track or too many track points in total. This is not uncommon when using PN series tracks on a Garmin device. Delorme devices don't really worry about the number of points in a track and consequently depending on speed and time an individual track can have more than 100,000 track points. Garmin is more frugal and even on the new devices limits you to 15,000, or 10,000. The older devices are even worse with 500 point limits. There is also a limit on the total number of track points allowed on a device.

Using BaseCamp just connect the tracks adjacent to one another into a single track. Then filter the individual and combined tracks down to some number of points less than the individual and total point limit on the Montana.

Using the Delorme Topo 9 or 10 software you could put all the tracks into a"draw layer" and then put that on your Montana as a map overlay. That way they don't even count as a track and they will all appear on your screen.

Double post.

Yes. How can I filter the tracks down to less points?

I'm not sure how to go from a draw file to a map overlay for the Montana, but that sounds like what I need to do, what I would like to do. But I haven't figured out how yet. My 218 point file is a draw file anyway, I only converted it to a GPX because I figured that was the only way the Montana would accept it.

You can filter the tracks in BaseCamp by opening the properties for a track (Right click & Open, or double click on a track icon) and selecting the "Filter" button.

Thanks. Sorry for the double post.

According to the specs, as well as according to my experience, Delorme PN-60 devices will only record a total of 20,000 points per track file before starting a new file.

Thank you 39Steps you are correct.

I ignorantly assumed that the six digit number following the date in the PN-60 track name scheme was the number of points contained in the track when in fact it is not. It is the time the track was written to the Delorme device. My ignorant assumption was further bolstered by the length of time it takes to open one of those tracks on my PN-60. Should have checked; my bad :(

It seems like the only solution to my issue would be the creation of an overlay map. Any clues as to how to do that?

Edit: Made some progress using Javawa GPS IMGfromGPX. I made an overlay map. Now the only issue I have is that it seems I can only add 1 overlay map at a time? Is this because my Montana can only take so many overlays at once perhaps?
