Q: Will this work with Windows 10?
A: Yes! And as long as you have an internet connection, you don't have to install any drivers. Just plug in the adapter and it should work.

Q: Will this work with my TV or my car stereo system?
A: Sorry, this device will only work when plugged into supported Windows or Linux computers, including Raspberry Pi with Raspian. Even though TVs and stereos have USB ports, they don't have the necessary drivers to support this adapter. If your car stereo takes a similar-looking Bluetooth dongle, you'll have to buy that exact adapter from the stereo maker or car dealer.

Q: Will this work with Mac OS X system?
A: Unfortunately, no. All recent Mac computers are designed to work with their built-in adapters, and won't work with this one.

Q: Can I use this together with my Windows computer's built-in adapter?
A: No. Windows can only support one Bluetooth adapter at a time. If you have used another adapter on the computer all drivers for it must be removed before plugging in this adapter. Any internal adapters must be disabled. We can help with this.


1.Windows 8 automatically finds and installs the latest drivers when the BTD-401 dongle is plugged in for the first time. Windows 10 7 / Vista / XP users need to use the included CD (or online links) to install the drivers.

2.If you need to transmit audio file, "BlueSoleil" software needs to be downloaded.
