i've seen these on ebay 84 86 87 Buick Grand National Type T Delco Radio IPOD: eBay Motors (item 160454989546 end time Jul-18-10 17:00:00 PDT)and mentioned on this board as well. i already have a stock radio and don't want to buy another with the aux input. does anyone know how to make one of these? i assume its only a few bucks in parts and some soldering. are there any other solutions to use an ipod with the stock radio?
