Yes, I did leave the dark side for a 9500i last fall
I just bought a 2005 745i BMW that has metallic tint in the windshield, causing the GPS feature of the 9500i to continually seek the satellites. It rarely connects and when it does it drops it pretty quickly. I enjoyed the 9500i, but since i can't utilize TruLock, I want to go back to having those lovely arrows on the V1.
I will probably put the 9500i on eBay and pick up a new V1 from Valentine after it sells.
