Hello, Thanks for all of the great info here.
I just bought a 2012 Sahara JKU with a blown engine (my first jeep), put in a complete engine out of a 2014 with 50k miles on it, working out a few of the bugs (my heater/ac doors going through a full cycle every time a door is opened

) and just getting around to the 430N update (I don't think this unit has ever been updated). Showing GPS 2.9, text 2.6, audio 2.3. and firmware of 33.00.41. Map is from 2011.
I have read this entire thread top to bottom at least a few times now.
I have downloaded the 2020.20 unlocked (thank you). I have also downloaded the 50.x firmware. A few questions:
Will this map version work properly on my current software (gps 2.9)?
Second question, i saw a link for 7.11 GPS (which I downloaded), but read a post that said one must go 3->5->7. Does anyone have a link for 5? Can I go from 2.9 to 5 to 7? Are these appropriate for a 2012 RHB?
I believe that junction views will work properly on this unit with 50.x.x, yes? If so, which file in the link for 2020.20 is the JCV?
Please confirm my steps are correct (which I will add to based on answers to my questions above):
Update GPS software (before or after map update or not at all?)
Update map first staying on current 33.x firmware version
Formatted Fat32 USB with \Garmin\gmapprom.img and \Garmin\jcv\(filetobenamed.jcv)
Assuming success, update to 50.x firmware (which I downloaded from MyGig onto a formatted USB Fat32)
Are there updates available for voice?
Will any of these updates fix the problem with the GPS time that started in the April time frame (before I bought the jeep)? According to Garmin they have no plan to fix it for these older units, GPS date is wrong and can't be set manually, which puts the time off by 1 hour (due to it not having correct date for DST adjustments).
I very much appreciate any direction, links, insights before I pull the trigger.
Thanks,
Steve
