+MrPeepers310 Posted August 1, 2008 Share Posted August 1, 2008 I have a Colorado 300 and I feel the basemap of the the world is pretty useless to me right now. Is there any way I can remove the basemap from my Colorado and replace it with another map? Even if i could back it up that would be great! Thanks! Quote Link to comment
+Red90 Posted August 1, 2008 Share Posted August 1, 2008 There are no more detailed "basemaps". There is no need to remove it. You can add "detailed" maps if you want. Both can exist on the unit at the same time. Quote Link to comment
+MrPeepers310 Posted August 1, 2008 Author Share Posted August 1, 2008 Well i want to put the topographic map on it instead and it doesn't have enough room. So i want to remove it. Quote Link to comment
+twolpert Posted August 1, 2008 Share Posted August 1, 2008 Invest in an SD card. You can (and should) back up the entire unit. Just connect it to the computer is mass storage mode and copy the entire contents of the device to your hard drive. Quote Link to comment
+Red90 Posted August 2, 2008 Share Posted August 2, 2008 There is 350 MB or something like that free on the internal memory. The basemap is 90 MB. Why is this extra 90 MB the deal breaker on the amount of maps you "need" to add. As stated, a 2GB SD card is $15 or so..... Quote Link to comment

+RRLover Posted August 2, 2008 Share Posted August 2, 2008 Delete [drive]:\Garmin\gmapbase.img -- it'll save you about 80-90MB . GO$Rs Will it even turn on without a "gmapbase.img" file present, I'm thinking "paper weight" time may be neigh. Norm Quote Link to comment
+MrPeepers310 Posted August 3, 2008 Author Share Posted August 3, 2008 supposedly the colorado 300 has about 4 gigs of memory that i cannot harness. the topographic map itself is about 3.5 gigs. Quote Link to comment

Norm Yep, I've tried it and the map screen just comes up white. supposedly the colorado 300 has about 4 gigs of memory that i cannot harness. the topographic map itself is about 3.5 gigs. Not the 300. A 400t has about 4G of memory. The 300 has about 350MB as mentioned above. GO$Rs Quote Link to comment

The other folks have told you their solution, which works well, and is what is supported by Garmin. Now I can tell you that you can do what you desire. I have taken my Colorado 300 and deleted the internal basemap. Next I uploaded a 7 sate region of Topo maps from my Topo 2008 DVD onto my Colorado 300. Once those maps were there, I renamed them to be the same name as the original basemap file. Now, when I turn on my Colorado 300, I get the Topo 2008 view as if I had a Colorado 400t (for the states I uploaded the maps for that is). This configuration is not supported by Garmin, but it works quite nicely for me, and it allows the unit to startup a little more quickly since it doesn't need to load the maps from an SD card (which is slower than loading from internal memory).
