Maybe you can help me. I am trying to update my map on a 2015 Chrysler Town & Country with a model RHB15 unit. I have a few questions that you might help me with. I have downloaded all the files you had under "City Navigator North America NT 2017.20" and extracted them to a USB Flashdrive. I made the folders "Garmin" and "JCV". I put the gmapprom & gmap3d files into the GARMIN folder and all the JCV files into the JCV folder. I downloaded the "Garmin Unlock" and have generated the code. Here's the questions I have,
1) What do I do with all the other files that I downloaded? (srx, asr, sid, etc...)
2) What is "FourSquare?"
3) What are the G2S, SQLite, 3790 ASR, 3490 ASR, Truckdown GPI files for?
I am going to try and see if I can get it to do anything if it won't do anything I'll let you know and maybe you can tell me what I'm doing wrong. Thanks for your help in advanced.
Ok, I just went out and tried it. Here is what I got: The "Nav Update" screen came up but after a few seconds it said the map did NOT update, then a screen came up and said PND DID update. I'm guessing I have some files in the wrong place. I see in your photos that you have 2 files, what files do you have in those 2 files?
