Hi James,
I read your post on installing ACM and got inspired enough to do the same on my 2007 XK. However, things have not gone well. I installed the unit myself and brought it to the dealer to have the software updated. But when I got the car back, I did not see an "Aux" button in my Audio option. I am trying to figure out if the dealer did not do the job properly or if my ACM unit is not working. Do you see the "Aux" button even if you do not have any thing attached to the ACM unit? How about if you disconnected ACM? Any help on this issue would be greatly appreciated.
Thanks,
Rich
