Problems with the Co 300
The units work fine until you try to add other features or bigger files of caches or maps.
I have had too many problems with the Co300 to count, mostly due to the unit just not wanting to turn on. I think it might be related to the memory card and how the unit reads the card. I sent mine in for replacement, but will probably not be using the new replacementbut putting it up for resale.
I got a 400T and after downloading (or trying to download) City Nav, Topo 2008 local maps and Topo GB it locked down and died. Seems that the Topo 2008 saves files in a different format than the one installed, and when you try to save maps it crashes. Also if you kill the hidden map file on the unit the base maps also vanish. So the 400T also is on it's way back to Garmin(only way to fix the software just now).
The 300 does not have the computing memory of the 400t and the extra fancy stuff the 400t does lots of stuff that the 300 won't do.
Be sure that if you are trying to load software that requires an unlock code that you have already input to mapsource or the gps unit will both lock up. The program says that you can still download the software even without the unlock code, but that is not true.
Now another point, that I forgot to do. When you plug in either unit to your computer, go to one of the explorer screens and BACK UP the Garmin files to an external drive. BACKUP before loading anything.
Then if you lose a file you have backup.
The units also need to be run thru the firmware and software file updater at Garmin about weekly as new revisions are there for a reason. Both units had problems with the compass and the upgrades fixed them.
New model and lots of bugs. Glad I kept the 60CSx and loaded all the files. Does get frustrating when 40 miles in the country looking for caches and the machine says no caches but there is a waypoint nearby by the same name.
Cache on, Bill in WTx
