I have a conne with the HI-Line stereo in, sat nav, tv etc. I was thinking of upgrading the stereo with the large screen which has bluetooth, dvd player. If I have got this correct it is the Harmon Kardon system. Can anyone tell me is it just a direct replacement and will I still be able to use the cd player in the glovebox or do I need any extra bits, cables etc. Thanks
