RG Colorado Question

Hi Guys N Gals

Just a couple of quick questions regarding the new RG Colorado

1. is the alternator a constant out put alternator or a variable type? if Variable is there a simple fix to make it constant output
2. is the Bringo sat nav as bad as it appears via the one month trial app for your phone or is it better and easier to use once it is connected to the mylink?

I have asked these questions of holden, and the dealers eyes glazed over and I got two different answers from there service department regarding the alternator

Thanks in advance Peter...
