In one word: testmode, or lack thereof of a truly functional testmode in the x930bt.
In my old x910bt, and using the collective genius of the people in this forum, I was able to do the following to my old x910bt:
1) hack it and play any video content any time
2) completely eliminate any and all 'disclaimer' and 'driver warning' screens - yes, I get it, it's dangerous
3) put a mute navi voice button on the map
4) put an instant route to home button on the map
5) turn the arrow into a pic of my car
6) steering wheel controls - i know, nothing to do w/ testmode but so nice
Sure,
