Talk to Blakester on this forum. According to him, he has a PC3 on his 750 that came off of a 600. But I checked on the DJ site and the model numbers are different for the 06 750 and 06 600.
from what i have heard, the actual pc3 is the same just the base maps are different. but i have not tried it my self so i don't know for sure.
Correct, base maps are different but the units, connections, etc are the same. Make sure you download a map for your model be it 600 or 750 and your set. I bought a 600 and used it on my 750.
