Running macOS 10.4 on my MacBook, any time I unplug this device, my system crashes with a kernel panic. (This GPS requires a kernel extension, rather than a routine driver, and it is apparently written badly.

As advertised

Great product, very quick and easy to set up and use, with very quick response to any movement. Ideal for car or boat.

good products

Initially hard to configure and install to Raspberry Pi3 but have got it to work and picks up GPS well and updates time on Pi (albeit about 15 mins wrong!). Should be shipped with (or have download for) some software to check it's working/display location.
