We're sure a lot of you T-Mobile G1 owners have been interested in Google Maps Navigation since it was announced (to be fair, who isn't interested?). And when we told you that the fine folks at xda-developers had figured a way to port Google Maps Navigation onto the beloved G1, you couldn't wait to find out how to do the same. And now that we have those instructions, you're ready to get started. So here it goes (remember, your G1 needs to be rooted and have CyanogenMod 4.2.3.1), to quote xda-developers:
