Why would you want to?

The G500 software is certified to DO178B Level C, which puts it one step above your iPad. http://en.wikipedia.org/wiki/DO-178B

The Chelton code base is certified to Level A. Level A code can't take instructions from level C code because the level C code has a much higher likelihood of being wrong.

Chelton is no longer producing an experimental version of its product. Too much hassle for too little $$s. However the heart of the system, the software continues to be developed and enhanced for the certified market. If you are lucky enough to own Chelton hardware you get all the benefits of the highest reliability software in the industry. Chelton dedicates a lot of resources to software development and certification. Garmin dedicates a lot of resources to marketing.

I know for a fact that there are fleet operators that are removing Garmin products and replacing them with Chelton. The reason cited? Reliability.

Full disclosure, my company has designed hardware for Chelton but we have no financial interest in the company.
