On our 4th Impala but the "19, like its recent predecessors, has a great sound system BUT no option to play CD's. Anyone have a recommendation for a good after-market device I could buy to plug into the available ports? XM-Sirius is great but there are times I want MY music! Tks!
I poked around some on the web yesterday with no great results.
I see battery powered, portable CD players. Besides needing to maintain the batteries, you will need to connect its speaker out to the radio's aux-in, if that's possible. And aux-in may need a low input voltage level that's hard to achieve with the speaker output - you may need to add some scaling resistors to drop the voltage.
Ideally, it would be nice to find a unit that plays and powers itself via the USB port into the radio.
I would go to a couple stereo shops and see what they offer, just to get a feel for what is actually available.
During my searches yesterday (eg, "portable cd player with usb connection for car") I kept getting bum steers to units lacking half the features. So some hands-on at Car Toys or Best Buy would be my next step.
[Edit]FWIW, the last head unit I bought, for my boat, was AM-FM-USB - no CD player. Like Keller indicated in his post, I use a memory stick that has ~40 CD's burned onto it (with lots of room left for more), and leave the CD's at the house.
