I am still waiting on pioneer's avic f90Bt because they have to do a firmware update like 3 or 4 weeks out anyone else dealing with this. I have been waiting for 2 months now, any input on kenwoods DNX 8120 in how it compares Im getting tired of waiting.

Should I go with the Kenwood or stick it out for the pioneer?

That really depends on if the Kenwood has the features you require. I have long since lost track of Kenwood head units and their specs.
