Thank you for viewing. This is a Sanyo EXCEDIO head unit from back in the day, with a spectrum analyzer. Operation has been confirmed. The spectrum analyzer has several patterns. I've checked CD, radio, and MD functionality upon removal. For those interested in neo-classic cars, this has a charm that modern, multi-function decks lack. The round switch on the track side lights up blue, and the round switch on the volume side sometimes flickers blue. I'm not sure if this is intentional or a contact issue. Apparently, it's always been like this. The exterior of the unit shows signs of use, but there is no damage. Kenwood and Carrozzeria are popular, but Sanyo also sold many car audio products in the 1990s, so it will be nostalgic for those who remember that era. Thank you.
