hi there wanted know if you guys can help me with speaker wiring/color diagram for 2004 cadillac cts. thanks in advanced.
I have the 2009 CTS with NAV and 4g. It came with XM. I have a lifetime subscription with Sirius. I would rather switch the XM over to Sirius and pay $5 a month for the extra reciever than buy XM lifetime for $700+. XM is charging $35 every 3 months now. Can this be done using the factor system in the car? If I have to replace the factor system is it going to cost more than the $700 for XM lifetime? Thanks for any help you can provide.
Jerry, most late model vehicles do not have USB input on the factory radio. You would have to install an aftermarket radio that has a USB input:
After Market Radios with USB Input
If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2009 Cadillac CTS stereo installation.
My 2009 CTS has the basic XM stereo. It has no auxilary jack in the console. Does the back of the stereo unit have a USB input the I can attach my own USB cable?
