Have two quick questions regarding the Z110BT. These will be the deciding factors in choosing it over the Kenwood DNX9140 (or vice versa).
1) USB device file limitations. It is 255 folders with 255 files in each folder (so roughly 65k) on the DNX9140, which is perfect for my needs. The Z110BT's manual isn't too clear - it states a 16GB size limitation (which seems to be bunk as reported by some here), 300 folder limit (OK) and 2500 file limit (per folder? if not, NOT OK).
2) GPS quality. I've used Garmin handhelds before and am familiar with Garmin's routing quality and number of POIs. It looks like the DNX9140 can be easily "updated" (the quotes shouldn't require more expounding on the topic). The Z110BT seems to be an in-house, custom programmed, one-off kind of thing. Never having used a Pioneer nav unit before, I cannot ascertain its routing and POI database quality. Also can't seem to find anything about "updating" it.
Many thanks in advance!
