What Files supports my Garmin Device and which Files I should update?

Be careful interpreting Garmin's device tables as gospel, they are a good general guide but not all accurate.

I also have handhelds GPSMap 66i and Rino 750's that like the RV770 are all listed in Garmin tables as limited to only a 32GB card.

However both the GPSMap 66i & Rino 750's continue to work fine with 64GB & 128GB cards formatted FAT32. I'm able to view any location across the 68GB of JNX topo's I have currently enabled in them, plus the overlaid vector .img maps.

Disclaimer: Note that these are only my personal examples for illustration, not general recommendations. Best for anyone to test their own device to confirm for sure but be well aware of the map configurations and the device's performance and map tile & segment limitations as you could easily exceed them if you go beserk with these size cards. I purposely created my own JNX files large, with my tools typically around 1.3GB and it keeps the count down.

Often, indeed almost always, on the occasion of the release of a release of Maps the Forum is overwhelmed with questions (and therefore of Post) of the type: My Nuvì xxxx supports JCV? If Yes, what type? Can I install in my Nuvì xxxx 3DBuilding Map? Where to copy Maps? In which folder? Rating: 5
