Rexing CPW-42 Review: Wireless CarPlay & Android Auto Adapter

If you are tired of digging through your center console for a cable every time you start the car, the Rexing CPW-42 is designed to solve that specific friction. It plugs into your vehicle’s existing USB port and turns a wired CarPlay or Android Auto setup into a wireless one, allowing your phone to connect automatically once you are in the driver’s seat. Instead of managing a cable that can fray or get lost in the cup holder, you simply sit down, start the engine, and your phone pairs up. This is a practical upgrade for drivers who want a cleaner dashboard and faster access to navigation, music, and hands-free calls without rewiring their head unit. If your car already supports wired CarPlay or Android Auto, the Rexing CPW-42 is the direct path to making that experience wireless.

Who it's for

The Rexing CPW-42 is ideal for drivers who already have a vehicle equipped with wired Apple CarPlay or Android Auto but want the convenience of a wireless connection. If you are constantly dealing with tangled cables, struggling to connect your phone every morning, or simply want a cleaner look in your center console, this adapter is a practical solution. It is also well-suited for those who want to upgrade their existing head unit without the expense of replacing it entirely. By plugging into the existing USB port, the Rexing CPW-42 allows you to retain your current screen and controls while adding the seamless connectivity of wireless phone integration.

Who should skip

This product is not for drivers whose vehicles do not support wired CarPlay or Android Auto. If your car’s infotainment system does not have these features, the CPW-42 will not work, and you would need a different solution, such as an aftermarket head unit. Additionally, if you prefer a dedicated, standalone screen for navigation and media, this adapter may not meet your expectations, as it relies on your vehicle’s existing display. It is also worth noting that the adapter requires a stable USB power source, so if your vehicle’s USB port is prone to issues or is located in an inconvenient spot, you may want to consider a hardwired installation or a different product. For more options, you can explore other wireless CarPlay adapters to see if a different form factor better suits your vehicle’s layout.
