The Alpine CDA-9851 (sold on Crutchfield) is the only deck right now that actually has OEM Steering Controls integrated into the stereo.
This is true integration, not the cruddy PAC-SIWX (or whatver it's called) that uses infrared.
The Toyota to Alpine steering control box should be available through PAC in about 10-14 days.
You can also go to
www.alpine-usa.com to view the specs on this unit. Crutchfield doesn't mention the OEM controls on their site, but it does on Alpine's site. I have verified by talking to Alpine's technical support.
