First post here. Fantastic forum! I would like to confirm if CXNA 2013.10 is NOT compatible with CNNA 2013.20 via lifetime updater.

I upgraded my 2950LMT to the latest software and map to CNNA 2013.20. I loaded up CXNA 2013.10 and tried both full and small version. All I got for navigation options are "Drive" and "Walk". Finally I decided to download CNNA 2013.10 and replace the gmapprom.img file in the ".System" folder on Garmin. Now it works and I got the "Public Transit" option after I click "GO" button.

Right now, the voice command is not working for "Find place", "Find address" and "Find intersection". It can be fixed by switching gmapprom.img file to 2013.20 version. I haven't test if the junction view still works with 2013.10. What other files do I need to fully use the 2013.10 version? Or is it possible to revert back the updater to older version?

I am a long time user of StreetPilot 2720 (can hardly believe I paid $600+ for it and that was a good price). The new Nuvi is amazing. A lot is changed and this is a great place to get all the info. Thank you all!
