To keep costs down the Onyx can only connect to a max of eight satellites compared to the Sapphires that can connect to twelve.
The Onyx also has super low power consumption.
The bottom of the Onyx has a super-cohesive magnet, which allows you to place the unit on your car roof. One thing the unit is lacking is some sort of suction cup to install the unit onto a car's dash, though a piece of sticky tape should suffice.
One of the bigger pluses going for the Onyx is the huge selection of cable types available to connect to computers and PDA devices. In the above picture we have the USB cable type so we can use it with a laptop computer. You can also go with a PS/2 style serial plug for your computer also. As for PDA's most popular brands such as iPaq, Casio, Palm, Toshiba, etc are available.
The Onyx also works very well with Netstumber, making it easy for you to plot access points on maps with Netstumbler and your favorite mapping software.
To test the unit out we performed some TTFF (Time To First Fix) benchmarks. As well as using the unit in a car for a week. For comparison we added the results from a Garmen eTrex, Magellan SporTrak, and Royalteks Sapphire to the mix.

AS you can see from the results the Onyx's TTFFs were a little extended due to the fact that the unit uses eight sat receivers instead of twelve sat receivers.
The Royaltek Onyx GPS is a nice little unit that'll appeal to the budget minded consumer who would like to get into using a GPS.
