Is it possible to upgrade my Pioneer 3150 (Single CD in-dash). Yung pwede ng mp3 or vcd??

Another question is, wala akong RCA input? pano ko i-patch yung audio ng tv sa stereo?? What i have is the IP-BUS pang cd-changer, will this be of help kung kailangan ko i-patch ang audio ng tv??

walang kasamang cassete tape yung HU, kaya di ako makakagamit ng tape like device as input.

please help, kasi am planning to get tv.
