That might help huh =D Updated
oops, sorry about that. I did make a mistake. here is the proper commands
adb push build.prop /system
adb push build.trout.prop /system
adb push build.trout.prop /system/build.sapphire.prop
adb shell
cd /system/app
rm *Maps*
cd /system/sd/app
rm *maps*
rm *Maps*
cd /system/sd/dalvik-cache
rm *maps*
rm *Maps*
reboot
After it rebooted, adb install Maps.apk
Varified navigation worked. Then I pushed the .prop files from the 4.2.3.1.zip
adb push build.prop /system
adb push build.sapphire.prop /system
adb push build.trout.prop /system
adb shell reboot
For those still getting the INSTALL_FAILED_UPDATE_INCOMPATIBLE error... Instead of adb install Maps.apk, try adb push Maps.apk /system and then install the apk from the phone. Worked perfect for me installing from the phone when I kept getting the error installing through adb. All the other directions were followed exactly as above and my MT3G is back to normal + navigation.
What do you mean install the apk from the phone? I got the install failed error so I copied the Maps.apk to my sdcard and tried installing it through a file manager. That still didn't work though.
Here guys, all wrapped up.
Make sure you have CyanogenMod 4.2.3.1, by the way.
1) Unzip zip to desktop
2) Run Part 1.bat
3) When prompted to press any key, do so; the phone will reboot
4) When your phone is running again, run Part 2.bat
5) When prompted to press any key, the installation process is done.
6) Make sure GPS is enabled
7) Open Maps and press OK
8) Press Menu
9) Press Directions
10) Enter an end point
11) Click Go
12) Just under "Show on map", click Navigate.
13) When prompted to install the voice codec, do so.
14) Enjoy.

Alright... i've yet to be able to identify the specific lines yet... but here you go.
I was able to get navigation using the 2 build props attached.
I used SU File Browser and adb to do this. You can do it all with adb but between the 2 i was able to do things faster.
Mount system as rw
delete build.prop and build.trout.prop
(or you may modify yours to match, and skip the next step)
push the new build.prop and build.trout.prop to /system/
delete /system/app/Maps.apk
delete /system/sd/app/com.google.android.maps.apk if present
delete /system/sd/dalvik-cache/data@app@com.google.android.apps.maps.apk@classes.dex
REBOOT you have to reboot for the phone to re-read the build props
install the new maps.apk --- i did adb install <path-to-Maps.apk>
if you do not get Success then you missed something.
update: after all is working.. you may put your old build props back
<snip>
Finally, remove the <package></package> section for com.google.android.apps.maps by editing /data/system/packages.xml.
That will clear up the INSTALL_FAILED_UPDATE_INCOMPATIBLE.

Hey after wrestling with Google Voice not working with the changed Build.props I found out a quick and dirty workaround. Just go back to Google Voice 0.2 and the build.props aren't a problem!
Get it here: http://xdaforums.com/showthread.php?t=577163&highlight=Google+Voice
Just do adb install -r com.*0.2 APK FILE HERE*
I'm back up and running now! Hope this helps!
grab the build.prop and build.trout.prop from this rom http://xdaforums.com/showthread.php?t=583001
I pushed them and now facebook works and I still have navigation working.
