I hade my oil changed yesterday and also had the wheel click TSB done. I got a 2013 SRX as a loaner and I really liked the NAV interface as compared ours. Map graphics are better, bluetooth interface is better, etc. It looked like all of the hardware matches what I have in my 2012 V Sedan so I was wondering if it is possible to upgrade the software to what the SRX has. I am not talking about a DIY hack, I would like to know if Cadillac can and will do this. BMW used to upgrade my software when I had their car and I was hoping we could get the same service.
