Product type	Where to look
Car Electronics & EV Charging	Look on the back or underside of the unit. EV chargers have a rating plate on the side of the enclosure that lists model, voltage and amperage.

Getting the official Kenwood Car manual

Kenwood Car publishes product documentation on kenwood.com. Search there with the full model number from the label, then look for a documents, manuals or downloads section on the product page.

If your model isn't listed, try removing the last few characters, which usually only indicate color or region. For discontinued models, look for an archive or legacy products section, or contact Kenwood Car support directly.
