GXL Landcruiser 105 Series Diesel

Need some advice regarding 105 Series Diesel GXL Cruiser. Just doing some research into different year models after 2000, does anybody know of any major changes internally and mechanically? I know the 1HZ motor has not changed, was more interested in gearbox or internal features such as stereo, air con etc. From memory some later models recieved rear air con vents and blue tooth etc. Any info would be appreciated.
