I probably burned half a tank of gas trying already.
JoeSchmoe007 you don't mention what model year you have...
(and it's not in your profile)
NOTE: This is only good for model year 2011 & 2012 430N radios. They changed something in the model year 2013 & 2014 430N radios. Those radios require Garmin software v5.
I don't run the engine and I've even done this work in the winter and not killed my battery (though I ran an extension cord in through the window and ran a space heater to keep warm).
If you have push-button start you can press the button twice to get to the 'run' mode without the engine running, but the system will shut down after 30 minutes so set a timer to restart once it shuts down.
"PND did not update" is a normal message because there are no map updates on the CDROM, only the Garmin and radio updates.
What I did:
My radio was at v50.
I inserted the v33.02.01 CDROM.
It asked me if I wanted to update HDD baseline files.
I chose YES.
It works for a little while, then starts updating Garmin files.
After a few minutes it produces the "PND did not update" message.
Radio reads files for a few more minutes, then prompts me to 'update' from v50 to v33.
The radio restarts.
Automatically comes back up and starts updating the radio firmware files with a progress bar.
Once the 'update' completes the radio shuts down and shows the time (I have that set in my settings, to show the time when the radio is shut down).
At that point I press "LOAD" to eject the update CDROM.
At that point instead of looking at the actual Garmin software version, I tried the 2016.10 map update and it worked.
It was only afterwards that I went into the settings and looked at the Garmin software version and noted that it was actually at v3.
