I know i saw somewhere in the past a company that completely reworked the audiNAV, i believe it was an RNS-E, they completely rebuilt the operating system and such, it was really neat.

I didnt really pay attention to it back then because i was still obsessed with my GTI, but now that im considering getting an RNS-E i think it would be cool.

Does anyone know of the company(s) that does this?

anyone have any other experience/detail?
