I'm wondering how many square miles of imagery they are/can cache with the limited size of the onboard storage.
From loading satellite imagery onto my handheld GPS receiver, at highest resolution it averages out to about 15 MB of imagery per square mile. Given that the claim was for a mere pittance of 3,000 songs (likely computed for short tracks with highly compressible music), I can't imagine it being much more than a 16 or 32 GB flash drive. The real specs are probably out there somewhere, but haven't found with a quick search.
So going with that, it could cache perhaps 1,000 to 2,000 square miles of imagery. That sounds like a lot, but that only covers an area somewhere between 30x30 miles and 45x45 miles. At least for me, unless their caching optimizes to retain areas most frequently traveled, it would constantly be dumping pages from the cache to save whatever random place I was driving to each day (I usually drive about 50 miles a day, and rarely to the same destination area for more than a few days a month)
I'd prefer to have some simplistic interface (similar to max charge level) to allow me to set the percentage of storage to dedicate to music vs caching.
