To all E38 owners I wish you all a very good day. I have a question that I need advise. Can anyone advise me, I own a 728i double vanos 2001 E38. I would like to change the radio on my car to the one with the monitor. I know I can find them at the potong kereta shop. My question is, is it a direct replAcement or is there any modification involved . Pls help me, I need advise and if anyone has any of the monitor unit for sale, I'm interested in buying. Kindly e mail me at kadir@scicaviar.com or I can be contacted at 0122039777. I would really appreciate it if anyone can help me. Thank you
