Overview
The Rocketek NK-GT4S-3 is a 6-in-1 dongle that converts a car's factory wired CarPlay into wireless CarPlay or wireless Android Auto, and adds built-in Netflix and YouTube apps plus a TF card slot for offline video or music. It is not compatible with BMW or Tesla.
This one goes further than a plain CarPlay converter: it streams Netflix and YouTube over a phone hotspot or car Wi-Fi, and plays files from a microSD card up to 256GB when there is no connection at all. Rocketek is explicit that streaming and CarPlay or Android Auto cannot run at the same time, and that the box does not support installing other apps beyond what is built in.
- 6-in-1: wireless CarPlay, Android Auto and streaming

- TF card slot up to 256GB
- Not for BMW or Tesla vehicles
Who it's for
Drivers who already have wired CarPlay and want wireless CarPlay or Android Auto plus a way to watch Netflix or YouTube while parked or charging. Not for BMW or Tesla owners, who are excluded outright.
Pros and cons
- Adds built-in Netflix and YouTube on top of wireless CarPlay
- TF card slot supports up to 256GB for offline playback
- Switches between CarPlay and Android Auto in one box
- 24 months of after-sales support per the listing
- Not compatible with BMW or Tesla

Performance notes
The box runs on a 4.2GHz Wi-Fi module that Rocketek says recognizes and connects to a paired phone within 10 to 15 seconds. It switches between three modes, wired to wireless CarPlay, wireless Android Auto, and wired Android Auto, but Rocketek is clear that Bluetooth needs to be off on the phone when setting up the hotspot connection for streaming, and that streaming and CarPlay or Android Auto do not run at the same time.
