Teyes Android Head Unit CC3 USB capability

I haven't installed my CC3 in my vehicle yet, but have been setting it up on my dining room table. I have tried a couple of 64Gb USB drives and the unit reads them fine. I also tried a 4Tb external hard drive and it reads that fine too even though it is formatted as NTFS. And if you are wondering it is running Traveller with the 2021 maps just fine.

HI we have one of the original Teyes SPRO 10' bought online from AliExpress a couple of years ago for our LC200 (2009 model). It's still going awesome. Ours came with a large internal storage somewhere near 100GB we only have a small 16GB SD card with a bit of music. We run the ExplorOz Traveller app as our mapping/navigation app and since the map file downloads for the whole of Australia in the new vector EOTopo 2021 mapset at high resolution (1;2000 scale) fits in just 5GB there's no need to use the external storage.
