The original poster won't be able to verify if the cruise control or the ambient lighting will be affected as he drives a ZS, I have cruise control and the ambient lighting in mine, not so worried about the lighting but wouldn't want my cruise control to be affected as that could end up quite dangerous. I'm seriously considering buying this unit as I have the very standard unit in mine atm, the small red screen and lacking bluetooth/usb. It doesnt have the sleekness of the updated fiesta radio onscreen but seems to have a lot of very cool functions. Chase - when you were buying it, how much would it have cost for the feature for the steering controls to work? I enjoy having them close to hand on the steering wheel and they would come in handy especially if you have a touchscreen.
