+Phipps Family Posted February 24, 2008 Share Posted February 24, 2008 Is the only difference between the Colorado models what map they have pre-installed? Quote Link to comment
+GOT GPS? Posted February 24, 2008 Share Posted February 24, 2008 300 > Preloaded World Basemap 400c > Preloaded Coastal Waters 400i > Preloaded Inland lakes 400t > Preloaded Topo 2008 maps <2.7 gigabytes> Quote Link to comment
+The Other Stu Posted February 24, 2008 Share Posted February 24, 2008 That's not exactly true. Read the info around the forum. I believe that the 400s have considerably more built-in memory (800mb?) than the 300c (384) Quote Link to comment
+Phipps Family Posted February 24, 2008 Author Share Posted February 24, 2008 Internal memory isn't really a big deal to me as I can easily add an SD card. I don't really want any of the maps, since none come with CN preinstalled, that come preinstalled, so I'm thinking the 300 is probably suitable for me. Quote Link to comment
+qlenfg Posted February 24, 2008 Share Posted February 24, 2008 (edited) According to Garmin's site, the hardware is identical. The difference is the pre-loaded maps, although they also have differing amounts of internal memory. Unfortunately, Gamin site only shows the memory amount for the 300. Unless you are into lake or ocean fishing, sailing, etc... there is no reason to buy the 400i or 400c. If you are going to do caching and hiking and need to topo maps, the 400t would be the one to get, but if you want to cache and use the unit for travel and don't need the topo maps, get a 300 and buy the City Navigaor NT maps. I chose the 300 and got a cheap 4 gB SDHC card for any maps I may get in the future. Edited February 24, 2008 by qlenfg Quote Link to comment
+Phipps Family Posted February 24, 2008 Author Share Posted February 24, 2008 Thanks for the replies!! I've started saving my pennies. I haven't decided whether I'm going to get a 60CSx or the Colorado. I've got a while until I have the funds so I guess I'll make the decision then. When you buy CN on a SD card are you able to run it on a computer or is that only the maps for the GPSr? Quote Link to comment

From this thread however I notice 2 things. 1. An SDHC card does NOT work. The max is 4gb NON-HC. Not that it makes much odds. 2. The TOPO maps (on the 400t) are 3-4gb in size. If you get seriously into having other stuff, then you're not gonna have much change! In the UK, the topo maps are 1/2gb and they're not much use (we're all used to O/S maps and I've yet to see any other world map in as much detail) HTH Quote Link to comment
+qlenfg Posted February 24, 2008 Share Posted February 24, 2008 Don't know about *all* SDHC cards, but I have a 4 gB Kingston SDHC and it works fine in my Colorado 300. I borrowed some maps and loaded some photos on it and it works great. Kingston model SD4/4GBKR -- snagged it at Best Buy because I was in a hurry. Quote Link to comment
QuigleyJones Posted February 24, 2008 Share Posted February 24, 2008 Did you load more then 2gb worth of maps? Quote Link to comment
+qlenfg Posted February 24, 2008 Share Posted February 24, 2008 Not yet, but I could do that. There is still a segment limit of 2025, no? Quote Link to comment
+Red90 Posted February 25, 2008 Share Posted February 25, 2008 I don't believe it is possible to COMPILE more than 4 GB of maps. AFAIK, the IMG format can only allow up to 4 GB. Quote Link to comment
+GOT GPS? Posted February 25, 2008 Share Posted February 25, 2008 I had the 400t, but that had problems, and I just got home with my new 300, and it is working ok. The 300 has a good Worldwide Basemap, that I like and I am going to put both City Nav 2008 and TOPO 2008 on the memory cards. So I think the 300 is a good choice. The Topo on the 400t was 2.7 GB when I had it, and there were about 300 megs free of memory. Quote Link to comment
toddm Posted February 25, 2008 Share Posted February 25, 2008 Interesting, I know you can't complile more than 4gig of maps on mapsource but could a person load say 3 gig of topo 2008 and then put say 2 gig of city nav on an 8 gig SD card and use it on the Colorado 300? The 400t starts to look a lot better if you can't use more than 2 gig of maps on the SD card with the 300, because it comes with topo preloaded, and I think the entire city nav will fit under 2 gig. Though I guess in all honesty I never had a problem getting more than enough topo and city data on a 2 gig card on my 76csx. Quote Link to comment
+bdejong Posted February 25, 2008 Share Posted February 25, 2008 SDHC will work. I bought a 4g micro SDHC witha n SD adapter at best buy because I didnt want to wait and the 300 found it and uses it with no trouble. As far as the limit, I dont know. I have mine loaded with city navigator and topo for my home state with no problems. I started to load the whole US, but I dont travel coast to coast all the time so why bother. I keep my loaded maps clean and lean. Oh, and I have a 300 as well. I opted for it since the memory cards are cheap and having the whole united states in the unit was not important to me.

+jotne Posted February 25, 2008 Share Posted February 25, 2008 I can confirm that an 8GB SDHC card do work. But as normal with Garmin , you can only have a 2GB file with maps. For the internal memory Garmin do often use several files, to overcome 2GB limit. gmapbmap.img (Base map file, can only be internal) gmapprom.img (Built in maps like City Navigator, only internal) gmapprom1.img (Built in extra maps, only internal. City Navigator EU and US need two files) gmapsupp.img (Maps you download, van be both internal and external on a SD card) gmapoem.imb (OEM maps, only internally) Conclusion: You do not need more than a 2GB SD Card, but you can use several cards. If you like many maps in your GPS, buy a unit with large internal space. You can rename gmapsupp.img to gmapoem.img and you will not overwrite your maps next time you transfere new maps.

+g-o-cashers Posted February 25, 2008 Share Posted February 25, 2008 This page of the Colorado FAQ should answer your question in gory detail. GO$Rs Quote Link to comment
toddm Posted February 25, 2008 Share Posted February 25, 2008 Actually the Faq does not really. It does not address if you can put two sets of map images on a 8 gig card and if those will be used by the colorado properly. For example while I realize you cannot have more than a single 4 gig image file. Could you install a 3.5 gig worth of topo 2008 as one image file, and then install another 2 gig of city nav as another image file on the same card as Jotne mentioned and get the colorado 300 to use both map sets at the same time? If not, then the 400t with it's 4 gig of internal space becomes an advantage if a person want's a lot of maps on their gps Quote Link to comment

It does not address if you can put two sets of map images on a 8 gig card and if those will be used by the colorado properly. Garmin states that 4 gigs is the max the Colorado will address. I've seen two people say that they got an 8 gig card to work, but neither stated if it was able to address beyond 4 gigs. I would just make the assumption that 4 gig SDs are the max, like Garmin says it is, and make your decision that way. Quote Link to comment
