As you all know by now, the Verizon DROID by Motorola has Google Maps Navigation Beta, which gives its users turn-by-turn directions, vocal prompts, speech-recognition and more. Well, if you have a T-Mobile G1 and can’t help to feel a little jealous, okay, lets face it, maybe more than just a little. Do not fret, you may have a shot at this new Google GPS app.
Apparently the folks over at xda-developers.com have figured out a way to make Google Maps Navigation Beta to work on the T-Mobile G1. Although Android 2.0 is only on the Motorola DROID, and still evading all other phones, the xda-developers have worked out this hack for you; G1 users.
Google Maps Navigation Beta only works in the US, so have in mind that this hack might not work with those G1 phones outside the States. If you like to know more about it, or even apply this hack to your G1, hit the link on the paragraph above to see how it is done. But remember to be careful and try this and any other hack at your own risk.

I had to reinstall Google Voice because I must of wiped earlier when I went to CM-4.2.4 build.
Anyways after its installed you use Maps like you would normally use and when you pick a destination you are given the old school directions, but then there is a button that says Navigate. I'm running Google Maps 3.2.1 as well and it loads super quick if anybody is interested.
I used a different set of direction from here, but I cant find them to link right now...
