Just got Miomap 3.3 installed. I put everything on a 2GB SD card, and just run it off of there. No rewriting the Pioneer files, so if I remove the SD card and hard reset, it just boots normally. Seems to work fine (including Bluetooth), except for:
1) The empty black bubble as others have noted
2) Text to speech seems to be disabled. Anyone know how to get this to work (I PM'd the post-er above who said they got it working too).
BTW, the 2nd torrent link listed above works much better. I downloaded the US and Canada maps (~ 1.8GB) in 40 minutes - almost 900k/sec. Awesome.
