I had similar issues with my NUVI 1350 until I adopted my current process. I use GSAK, GPX_by_Cache_Type macro, and POI Loader. To avoid any possible memory issues I installed an 8gb microSD card into the 1350 and load the caches on that.
1. Load all your Pocket Queries into GSAK.
2. Run the GPX_by_Cache_Type macro.
3. Run POI Loader and “Remove all previously installed custom POIs from your device.”
4. Run POI Loader again and “Install new custom POIs onto your device.”
Using this method you can load several thousand caches on the NUVI. All of the descriptions, hints, and some of the recent logs will be available, as well as the ability to search the caches by cache type.
