I just got a 98 Grand Prix but the radio doesn't work so I was searching for a new head unit and came across a really cheap double DIN head unit on ebay (from China so maybe I won't actually get it) but ordered it and was searching around the forums to find others who had installed a Double DIN in their 98 and nothing really came up for me to see - I found one guy on youtube that had one in a 2002 I think but wondered if I was just missing it here and if there was a write up on how to do it and all that wonderful stuff about the modifications to make it work! Thanks in advance for all your help!
