I just purchased a new 2008 4Runner SR5 on Saturday. I told the dealer I wanted XM radio. When I went to take delivery Tuesday evening, they told me they tried to install the XM kit and only after installing it found out the head unit in the SR5 is not XM capable. Obviously, at this point a JBL system is not a possibility, since the amps, wiring, speakers, etc. were not installed at the factory. The brochure says a 6-disc in dash CD changer is available for the SR5 (non JBL - standard equipment on the Limited) which is satellite capable. The dealership claims this stereo does not exist, but it is right in the brochure and on the internet. Does anyone have this head unit, and if so does it work with XM and an SR5? I still have not taken delivery of the vehicle and said I would not until they provided me with what I paid for or proved to me it was impossible to provide. I am planning on going back over to the dealership tomorrow to talk to the consumer relations manager and service manager. If anyone has any ideas, please let me know!
