Hi,
I'm a new owner of a MY2010 XKR, and I installed JLR SDD v138 to recalibrate my seats and program a new key. Worked very well!
I also explored engineer mode and CCF editor. And there I have 2 questions
1. I wanted to activate AUX input. Enabled it in CCF, uploaded it to the car, but no AUX button showed up in my audio interface. It's still enabled in CCF though, is it normal?
2. Concerning the speed limiter parameter, I'd like to change it for track use, but it's strange. I have choice between 2 default settings 250km/h, 110 km/h, and plant limiter only. My current parameter is an odd "0X8". Someone knows what it means? How to set it to 300km/h? Do I need to input another hexadecimal parameter? Or maybe us a newer version of SDD?
For AUX activation you can use this (but it would require SDD v146-up. Latest one is 164, this mod works with it too. Activation of the SDD is another question) X150 XK/XKR retrofits, AUX, Reverse Camera, DAB+ Digital Radio - Jaguar Forums - Jaguar Enthusiasts Forum
Speed limiter is hex value to dec + 108kph. So 0x8E is 142(0x8E hex to dec)+108kph = 250kph. 0xFF is reserved, so the max value is 0xFE, which would mean 254+108 = 362kph.

Got a SDD Software v160 with Engineering access, and in integrated CCF editor mode, I was able to change the maximum speed parameter to 300.
Earlier version V138 didn't allow that. So it's all good.
For changing value in hexadécimal I probably need to use an external CCF editor, but I don't need more.
Thank you for your help!
