Our OEM radio still works but the LCD display cannot be seen and is mostly burnt out, its slightly visible driving at night with the interior lights on. Overall still very happy with the sound and I don't think we have a Dynaudio system but it does crank up and has the multiple 6 CD disk changer. I could get a used OEM radio but want to step up and have bluetooth availablity for our Iphones. I did some searching on this site and others and viewed several head units via Crutchfield but cannot seem to confirm a new head unit will be able to utilize the stock 6 CD changer? We still play quite a few CDs in the vehicle and would like to keep this option available unless it really is not worth it. If anyone knows or has a recommendation please let me know thanks.
