Driving app similar to one on Droid X

[JFS83]

Looking for a map app that worked like the one on Droid X when it was docked? Tried CarHome but if I turn on Maps it does not replicate the Droid X. Anyone know what app will replicate for my Moto X? Also, why doesn't the OS support stay awake thru a setting plugged in or not? Want to keep it on while driving instead of sleeping but only when driving.
