The Kenwood is at this moment I think the best all-in-one unit. Pioneer will come in march with the ne model of the HD3 double din unit and I think that will be a big competitor.
Although Kenwood has the CAW-PS1200 steeringwheelinterface which also connects the Kenwood with the multifunctional display, Pioneer has not that possibility as far as I know.
There is another trick to make it work properly needed, this I found out with a Peugeot engineer and we want to keep this ourselves for now. (sorry)
The frame around the Kenwood is from
