IO5 to IO6

[laaubin]

Hi,

I'm relatively new here so forgive me if this has been covered.

Does anyone here know the items required and the part numbers to upgrade the OnStar Nav radio (IO5) to the full Nav (IO6) system?

I've seen where it's only a cable and in other places you need to get a number of parts.

If anyone has any experience with this mod I would really appreciate as much info as possible so I can go ahead with this mod.

 

Thanks ahead of time for any help and info.

I think there was a conversion for sale in the "For Sale" section a while ago. Need HMI module and antenna. And some programming.
