That screen was posted by catymag as an example only to show you what it looks like. As she stated, it's from another nuvi model [a 465, not even JCV capable] and it wasn't meant for you to compare it to your Inventory as such.

Every enabled 1xxx nuvi is capable of using JCV files equally well from either folder, sd:/Garmin/JCV or unit:/.System/JCV so please back up your favourites and then either [Only registered and activated users can see links. ] or [Only registered and activated users can see links. ] on your 1350.
