I have recently bought a lovely 53 plate 4.2 V8 S-Type. Only 89K on the clock and has been owned for the last 12 years by a friend who due to kids cant and doesn't use it anymore and it has been sat for a year.   The car was used by Jaguar for the first year, then sold to my mate. Its Black with Black leather, Jaguar Voice, Sat Nav, Climate, etc. I have refurbished the wheels, mopped the car, changed plugs, oil & filter, fuel Filter, ATF and Filter, I have the headlights to resolve bit foggy (but have the 3M kit).   The issues I need help with if you would be so kind is.   The car originally had the phone module but this was removed due to a conflict with Jaguar voice. I would like to re-instate this. I have ordered one but its not the right one, my VIN number ends in HM99114 I have the 6 cd changer, sat nav bracket and a space above with four bolts which I assume is where this goes?	The 6 CD Changer will not eject the cartridge, do I remove and try to get it out or just replace?	The single slot CD will not accept a disc again, remove or replace?	 I am replacing the heater valve as the Aircon blows Sahara hot all day, I guess that its likely the CCU will need doing as well?	I would like to put a stainless system on the car and appreciate the growl a little more (note "a little") ideas?	I am replacing the steering wheel with the wooden/leather one, how does the old one come off?	Up to date sat nav disc?Ideas and suggestions are welcome, I've done a lot but I'm hitting a wall with these items.   Thanks in advance.   Matt
