Hi all has anyone done a upgrade on a 2008 luxury if so what do you have and modification have you done and added please. 

Thank you in advance. 

Not sure there are lots of options, assume your system similar to my 2013 car, the head unit in the jag is hooked up to a lot of things so will probably loose some functionality if you can find a unit that will fit nicely .

Others may have more experience, but I struggled to find any real good options when I looked.

I upgraded my 2008 XF Premium Luxury to the top of the range Bowers and Wilkins setup.

I was lucky enough to have a donor car so the transplant was relatively painless. The head unit does need to be changed to the multi disk version,

All the wiring was pre-installed with the exception of the centre dashboard speaker and it was no biggie to lay in a loom for that,

IIRC, it took 2 hours from start to finish, plus 20 minutes programming with SDD.

Overall, the B & W was well worth the time effort and cost.  As far as cost was concerned, the breaker who had to donor car asked for £50 and I could take whatever I wanted.
