I have a Colorado 400t that is experiencing sporadic shutdowns. Sometimes it happens as I am navigating through menus, other times I'll take it out of my pocket and find that it powered off by itself. I thought it might be the batteries since I'm using rechargeable Energizer 2500mAh NIMH but the problem also occurs with regular alkaline and lithium. This Colorado has also had problems correctly reporting battery life. I'll put in a fresh set of batteries and get a warning that the batteries are low five minutes later but the unit stays powered on for hours. I haven't seen this problem in the colorado wikispace issue list so I'm not sure how common it is. This Colorado is from REI with S/N 18XXXXXXX. Is this problem likely caused by Garmin's hardware, bad batteries, or a software issue?

Can you describe the free 24k maps you mentioned in more detail? From what I can tell the only 24k Topo maps Garmin offers are the National Parks East/West series. What are the options for 24k topographic maps that cover areas other than just national parks and can be loaded onto a GPS like the Garmin Colorado?
