You CAN update the USB compatibility with your car, which should solve the USB issue. 2011 Cruzes were most likely released with an earlier PDIM with DB/DB or lower HW/FW.How about the fact that the Play/Pause button does not work for the iPod ( at least for the 2011)? I drove all the way home without selecting the artist I wanted to hear. Sorry for the rant. I just think the software should be update to all the Cruzes that have the crappy software.
See the link below to do a quick and easy upgrade to your iPod functions, as well as add A2DP to your car. This module will bring you car up to DB/DD.
