How easy is it to do?

 

In regards to the fitting, does it require a fitting kit to sit in the existing console where the bolero sits?

 

Has anyone done this to an octy 2?

I had to buy a new surround and one legend Aussie forum member fitted and coded it for me kindly.

Common upgrade in Mk2 Octy and lots of info on here about it. Physically straightforward - pull Bolero out, unplug connector, plug in Columbus and GPS aerial and push it back and tighten screws. You will need a bit of coding with VCDS to tell the car you now have a columbus if you want all its functionality. Beware battery drain issue in pre 2008 cars and you may want to add a Fakra lead for pre facelift cars with single aerial input. As per previous post you will need a new fascia to finish it off.

Awesome!

 

Thanks for the help, i'm sure it's a worthwhile conversion, i currently don't have bluetooth audio streaming so i feel for the $1000 nzd for a module it will be similar for a whole new radio!
