I'm thinking about the future and what to do if my current head unit craps out... and the 2012+ head units seem to be the same price as my 2008 unit. That gets me thinking about swapping in a hard drive based unit to replace what I have now so... has anyone done this or know if it's been done?

Any GM techs that can share some input on this?

Did a search with no luck.
