Good Evening. . .I have a Nuvi 1350 with 5.90 & B0972-00. . .I am currently downloading the 2014.20 map. I had inquired about where to get the JCV files for this update and was told that my nuvi doesn't support these but. . . .I could patch my firmware to enable it.
WOW - this thread is really long.. . .I have attemted to read through and try to follow all of the updates but I am feeling a little over whelmed. My computer does have Windows 7 so do I just need to stop there because I can't use the software?
I would greatly appreciate some advise and directions for modifying. . .Thanks so much in advance.
PS: I also have a 255w. Can I update/upgrade it?

Yes, you can enable JCV in your US 1350. JCV is the only feature not already enabled in it. Firstly upgrade the fw to the current version 6.20 [you can use WebUpdater to make it easy], then the simplest way is to dl the SD card files from the end of Post #1. The thread is long, but everything you need to know and the current links are in post #1 really. Win 7 is no problem, if you have any trouble just run as administrator and/or change compatibility setting to WinXP SP3. If you use the SD method then there is no problem anyway as there is no need to use your PC to load anything to the device.
As for your 255W, you can't use this splash or any equivalent. You maybe would like to convert it to a 465T 'Truckie's Nuvi' and get LA but not JCV [check it's got HWID 0827 and only use the original 2x5W boot.bin]. There are other methods using Asian 2x5W fw, but too many downsides with that imo.

Thank you - I updated the Nuvi 1350 to the latest software using the web updater. Then I downloaded the (13xx in 14xx 6.20 for JCV.rar ) inside the rar file is a folder named updater. Inside that was updater.exe and the xxx.rgn.
I then copied my nuvi's gupdate.gcd onto my desktop, deleted it from the nuvi. Put the Nuvi into diagnostic mode by pressing battery icon for 5 seconds and then connected USB cable to computer. Waited for the computer to recognize it. Then I double clicked on the updater.exe, chose usb, clicked ok, clicked yes. Process is complete.
Then I saw after nuvi reboots you can put the gupdate.gcd file back in thte .system folder. However when I went to do that there was already a file with that name there. So I assumed that I did something wrong. So I went through the whole process again and this time there was no gupdate.gcd file when I went back to add it. Maybe I didn't deleted it like I thought I did. . . .But now. . .
Where to I put the JCV files? Assuming that I did the first part correct.
I have gmap3d.img also. Can someone tell me where to put this?

Put JCV files in Nuvi /Garmin/JCV or sdcard /Garmin/JCV
If the folder does not exist then create it.
Lots of users make a mistake and call the folder JVC![]()

@SeptemberC
look at garmindevice.xml in Garmin folder, all files paths are listed in it.
You have to navigate to get to the good.

Thank you all for this extremely useful and simple tutorial! Successfully enabled Junction View (JV) on a US 1350T--working perfectly. Cool!
Now, I want to enable another US 1350LMT, but I have a question... Sorry in advance if this has already been asked and answered somewhere in this long thread. I didn't see it in the many pages--not the entire thread--that I've read so far. If already answered, please direct me to the appropriate post(s)--much appreciated. Anyway, my hesitation is that once JV is enabled on a unit that has the Lifetime Map (LM) feature, would future map updates downloaded via Garmin Express (GE) have the JCV files automatically downloaded too? Or would GE still recognize that the unit is a US 1350LMT, and not download the JCV file along with the maps update download? If this is the case, then it would mean that I would have to find and download the corresponding JCV file manually after each new GE map update? Thank you for any info.
