Wife's new GMC doesn't have CD player, most newer cars don't it seems. But she has a CD collection she likes. As a Christmas gift I'd like to find her a portable CD player that will connect to car's infotainment system by USB, Bluetooth, or even headphone-out jack. Ideally, this unit would also have a 12 volt power plug so it doesn't rely on two AA batteries or whatever. Employee at a popular consumer electronics big box store told me the other day that only option is an old school battery powered portable CD player and use the headphone jack to cord music to the infotainment system. Is this true?
