I found this thread googling for a fix to the 40MB of cache on my TP2...I don't like messing with binaries so I tried uninstalling and reinstalling to the storage card, it seems to default to /Storage Card/Application Data/GoogleMaps/cache now without modifying anything. Only difference is now I have to keep the memory card inserted to run the app but I didn't swap cards often anyway so thats no trouble.

Just remember to delete the old cache folder if it doesn't do it during the uninstall or it'll still be wasting 30-40MB and you'll still get frequent memory errors.
