Installing widescreen audio from normal audio in a BMW E46 3251 year 2005

[yuenkl]

Hi everyone! I have just bought a 2nd hand original widescreen audio from ebay and would like to know what else is needed to convert the old cassette desk into this 16.9" widescreen? Do we need extra wiring, module or etc. Where can I have it fitted in KL? Who should I contact?Please refer on this: [video=youtube;mnrv3PY2lCU]http://www.youtube.com/watch?v=mnrv3PY2lCU[/video]ThanksYuen
