Lotek420 Posted December 31, 2009 Share Posted December 31, 2009 Hello, I have a Oregon 400t with CN 2009 on it. I wanted to turn off the street maps and only see topo maps that are built in to the unit. If I go to setup and map then map information/select map. I only see the CN 2000 maps to enable/dissable. I do not see the built in topo maps option to enable. Is it possible I accidentally removed the built in topo maps? If so how can I get them back? Sincerely Loren Smith Quote Link to comment
+Tatooed Lady Posted January 1, 2010 Share Posted January 1, 2010 have you contacted Garmin directly? I would... Garmin.com of course, I'm confused a bit by what I'm reading (call it new year brain fog)...If I'm thinking correctly, you want to see nothing but the hills, valleys, rivers, etc...no streets, etc. I believe that the units will automatically show all the above, including streets...but for navigation purpose, CN cards (or other) are required. The topo map is built in, and I doubt you can alter that particular view. Did I just make sense? Geez, I hope so...I have the Oregon 400t, also...and I love the darned thing. Quote Link to comment
+facade66 Posted January 1, 2010 Share Posted January 1, 2010 Did you put the City Nav on the SD card? If you just sent it to the unit using Mapsource, then it will likely overwrite the preloaded Topo See what Garmin say. (Other than an unhelpful "you should have backed up the unit first ) On my 550t if I goto setup > map> map information select map, I get a bubble for the pre-loaded Recreational mapof Europe (you should get US Topo instead) a bubble for WW Autoroute DEM basemap and a bubble for the map I loaded onto the SD card. Touching the bubble then lets me enable or disable the map. Quote Link to comment
+SamSpade47 Posted January 2, 2010 Share Posted January 2, 2010 The maps are are just files. The TopoUSA map is a file called: X:\Garmin\gmapprom.img. It's a ~2.63GB file. (X: = your unit's internal memory) The City Nav file is: X:\Garmin\gmapsupp.img. It's a ~1.1GB file. (X: = my mSD card) I also have gmapsupp.img file on the internal memory which holds NWTrails and "other" maps. Garmin introduced additional naming options several FW releases back, but I haven't bothered with it. If you've erased it you can copy it back to your unit (if you have access to the file). Maybe you know someone else that has a 400T. If you don't know someone close by where you live... I'm sort of close by... Down in Redmond... I'd be willing to hook up with you and get you back up and running. Sam Quote Link to comment
+fegan Posted January 2, 2010 Share Posted January 2, 2010 If you just sent it to the unit using Mapsource, then it will likely overwrite the preloaded Topo Not likely as the default basemap is named gmapprom.img, anything you load with MapSource is named gmapsupp.img. On the more recent Colorado software updates you can rename the gmapsupp.img to an filename with an img extension, so you can have multiple maps and so you can easily identify them. I have about 6 additional maps on my Colorado 400t, including: City Navigator, 24k TOPO for Florida, and some custom trail maps I created. Quote Link to comment
+fegan Posted January 2, 2010 Share Posted January 2, 2010 Is it possible I accidentally removed the built in topo maps? If so how can I get them back? Yes, it's VERY easy to remove the built-in TOPO maps...if you accidentally delete the file d:\Garmin\gmapprom.img the base map will be gone. Your best defense would have been to create a backup of your GPS as soon as you got it. If you didn't create a backup...to get it back either find a friend who has an Oregon 400t or it will have to be shipped back to Garmin for repair as the file is 2.7GB, much too large for Garmin to e-mail to you.

+facade66 Posted January 2, 2010 Share Posted January 2, 2010 Aren't the maps keyed to the device? Whyever would you buy a t if you can simply get a friends unit and copy their map? (With the internet you have lots of friends ) Quote Link to comment
+splashy Posted January 2, 2010 Share Posted January 2, 2010 (edited) Unless you deleted files from the gps YOURSELF it should still be there, you might have deselected it. You cannot overwrite it with mapsource. Edited January 2, 2010 by splashy Quote Link to comment

(With the internet you have lots of friends ) No, the basemap is not keyed to the unit. However, the basemap for the 't' is so large it won't fit on any of the other models...so you would need to own a 't' to copy the TOPO basemap from another unit. Quote Link to comment
