Leave the Cable Behind: Still plugging in your phone before every drive? CB4CT-GY is a wireless CarPlay adapter and CarPlay AI box that turns the wired CarPlay or wired Android Auto already built into an eligible factory stereo into wireless, while adding HDMI output for a compatible passenger screen. After setup, it can reconnect automatically, so navigation, music, calls, and messages are ready with less cable clutter and one less thing to handle.
Check Before You Order: A quick compatibility check can save the frustration of discovering after delivery that CB4CT cannot be used or controlled in your car. Your factory stereo must already have wired CarPlay or wired Android Auto and support control through a touchscreen, touchpad, or compatible remote/controller. Not compatible with BMW vehicles, most Subaru vehicles, aftermarket head units, or wireless-only systems. Unsure? Send us your vehicle year, make, model, and stereo details.
A Calmer Back Seat: Long drives feel harder when kids or passengers have nothing to do. HDMI output mirrors the CB4 interface to a compatible headrest, visor, or passenger screen while you control it from the main display. It helps road trips, charging stops, and parked waits feel shorter. The second screen shows the same CB4 content, and HDMI is output only. Video is for passengers or parked use where permitted by local law.
Stay Wireless and Keep CB4 Online: Why should turning on a hotspot interrupt your wireless phone link? Two dedicated Wi-Fi modules give each task its own connection: one supports wireless CarPlay or Android Auto, while the other connects CB4CT to your phone hotspot or in-car Wi-Fi for online apps. Internet access is required, but there is less network switching and more time to enjoy the drive.
Made for Everyday Driving: Need wireless navigation on weekdays and passenger entertainment on family trips? CB4CT focuses on what most drivers actually use: calls, music, navigation, our selected apps, occasional split screen, and compatible media playback. A USB drive up to 256GB (not included) can carry music and videos for trips where mobile data is limited or offline content is more convenient.
Useful Apps, Clear Expectations: Waiting in the school pickup line, at an EV charger, or between appointments? Use our selected apps for online video, music, and passenger downtime without filling the system with software you may never use. This is a curated app experience rather than an unrestricted app store. Availability can vary by region, service, subscription, and software version.
CarPlay or Android Auto: Use Either: One car, two phone systems. CB4CT is a wireless adapter compatible with Apple CarPlay and also supports wireless Android Auto. Turn on Bluetooth and Wi-Fi, make sure CB4 is not already connected to another phone, select “CB4_xxxx,” then open CarPlay or Android Auto on the CB4 screen and follow the prompts. To switch modes, hold the CP/AA pinhole for 5 seconds: green means CarPlay; blue means Android Auto.
Two Views, Privacy When You Leave: Need one app to stay visible while a passenger uses another? Show two supported apps side by side. With Unlock with BT, authorize the phones you trust; the CB4 interface locks when no authorized phone is connected and can unlock when one returns. Anyone else needs the correct password, helping protect signed-in apps when the car is shared, serviced, or handed to a valet.
More from the Screen You Already Have: Need a quick answer, vehicle data, or control of a compatible accessory? Press the stereo voice button to open DriveChat for questions and supported CB4 actions. Pair a compatible Bluetooth OBD reader to view data such as speed or RPM, or use CIotHub with selected Bluetooth accessories such as ambient lights. Accessories are sold separately; DriveChat does not control native vehicle functions.
Power It Right, Drive with Fewer Interruptions: Does your stereo USB port cause unexpected restarts or connection drops? CB4CT needs at least 800mA. If factory USB power is weak or unstable, use the included Y-cable with an auxiliary USB source to help reduce interruptions. OTA updates support ongoing improvements, and your purchase is backed by an 18-month warranty and customer support.
LEAVE THE CABLE BEHIND Still plugging in your phone before every drive? CB4CT-GY is a wireless CarPlay adapter and CarPlay AI box that turns eligible factory wired CarPlay or wired Android Auto into wireless. After setup, keep your phone in your pocket or bag while navigation, music, calls, and messages stay on your car screen.
CARPLAY OR ANDROID AUTO—USE EITHER
Do different drivers use different phones? CB4CT is a wireless CarPlay adapter compatible with iPhone and also supports wireless Android Auto, so one box works with either system. Hold the CP/AA pinhole for 5 seconds to switch: green for CarPlay and blue for Android Auto.
MAKE LONG DRIVES EASIER
Are the kids restless in the back seat? HDMI output mirrors the CB4 interface to a compatible headrest, visor, or passenger screen for family trips and parked waits. Both screens show the same content. HDMI is output only; video is for passengers or parked use where permitted.
STAY WIRELESS AND KEEP CB4 ONLINE
Tired of choosing between your wireless phone link and internet access? Dual Wi-Fi gives each job its own connection: one supports wireless CarPlay or Android Auto, while the other connects CB4CT to your phone hotspot or in-car Wi-Fi. Use our selected apps for online video, music, and passenger downtime. For offline trips, use a USB drive up to 256GB for compatible music and videos (drive not included). Online apps require internet access, and availability varies by region, service, subscription, and software version.
TWO VIEWS, PRIVACY WHEN YOU LEAVE
Need one app visible while a passenger uses another? Show two supported apps side by side. With Unlock with BT, authorize trusted phones and let the CB4 interface lock when none is connected. An approved phone can unlock it again; others need the password—reassurance when the car is shared, serviced, or handed to a valet.
VOICE HELP AND SMART-CAR EXTRAS
Want more from your factory screen? Open DriveChat with the stereo voice button for questions and supported CB4 actions.
