Thank you for viewing. This is a Wi-Fi module that can be used with KENWOOD's Saizoku Navi. By turning on your smartphone's tethering and connecting from the car navigation system, you can obtain information online. It is very small and does not require a specific installation location. I used it previously with a Kenwood Saizoku Navi. I think it can also be used with a PC. Compatible with Kenwood car navigation systems: MDV-Z701, Z701W, MDV-Z702, Z702W USB Wi-Fi adapter USB Wi-Fi module Wireless LAN Thank you.
