Alpine CDA-9851
I forgot to mention that not only will the Alpine CDA-9851 work with your OEM steering controls, it will also run Sirius or XM.
I almost installed it but did not for a few reasons:
1) The unit only takes up 1 din (I prefer the factory look)
2) The unit is silver, not black
3) The OEM control box is not quite ready, but will be in about 2 weeks according to Alpine and PAC
