Can I turn off autocomplete/autocorrect for Google Maps?
Ok, I found a workaround. I am calmer now.

Use Spiffy Search from the Market. You can use it to search, then have it set to maps. It doesn't use your internet connection. 

Then,  edit maps settings so that the navigation icon appears whenever you find a location. 

My deliveries just became a little easier!

Btw, I use a Droid X on Page Plus, which uses Verizon's network. For 30 dollars, I have vzw coverage, which is essential on my job, 1200 minutes and 3000 texts, but only 100 mb of data, which is why I am so obsessed with conserving it. Now with this work around, I can email, websurf with opera mini, and navigate without going over my limit. It is a brilliant way to milk the big V for all they are worth!
