I always get "PND didn't update" and I am never prompted to update GPS software to 3.0. The rest of the software updates fine.
Does anyone have any ideas?
PS Don't use DVD to burn firmware - it will cause soft brick (just like described in the post above but I didn't notice). Or at least it did for me. The fix is to burn firmware to CD and use it (I initially used USB drive but GPS didn't update, so I tried DVD because couldn't find CD-R media immediately).
#1 - I've always used only CDROMs for radio firmware updates, then I use a Class 10 microSD card in a USB adapter for map updates (due to the large size of the map files). Another important tip, when burning the CDROM always use the slowest speed possible by your CD burner.
#2 - When updating the radio firmware, the "PND did not update" message is normal due to the fact that the firmware only updates do not have map updates included.
To be honest...
I forgot to check what my GPS software version is at.
[EDIT: Checked today while doing some yard work... My Garmin software is at v3.]
I ran the v33.02.01 radio firmware update (actually downgrade since I was at v50, but v50 doesn't allow map updates for some strange reason) and then used my microSD/USB combo to upgrade to the 2016.10 revised map upgrade (including the JCV/junctions file).
Prior to the v33.02.01 I could only go up to 2014.40 Garmin maps. Any attempt to try a later map update failed. My understanding is that Garmin changed the format of their map update 'img' files so that the older software in the radio did not 'understand' the new 'img' files.
Once I had the maps updated to the latest/greatest, then I upgraded the radio firmware again to v50 (I like the dark theme better than the blue theme in the v33 update).
I keep the v33.02.01 and v50 CDROMs because if I want to update maps again, I'll need to downgrade to v33, apply the map update, then upgrade again to v50.
Yes, it's a pain, but I've not had any problems to date and I've done the radio downgrade/upgrade process a number of times.
The radio downgrade or upgrade process takes about 20 minutes.
The map updates (with my Class10 microSD/USB device) takes about 1 hour and I don't run the engine.
I have the push button start. I push it twice with my foot OFF the brake so it goes to the 'run' condition and then I turn off everything that isn't needed (like HVAC) and set an alarm for 25 minutes. If you have the push button start, with the vehicle in the 'run' condition and the engine not running the vehicle will power down at 30 minutes. I set the alarm so I can go back out to the Jeep and power it back up immediately so the update is not interrupted.
