Sure, wireless CarPlay is a great resource, but it can require some serious time and effort tying into your vehicle’s speed-sense wire. Kenwood’s KNA-SPM100 adapter connects to your speed-sense wire through your vehicle’s OBD-II port, giving you the convenience of wireless CarPlay and more accurate GPS locations for your navigation apps. This adapter is not needed if your wiring harness or OEM adapter includes a speed pulse connection. The adapter works with select Kenwood radios with wireless Apple CarPlay.
