It looks like some came with an onboard Nav system, however I'm not so lucky. I would like to relocate the heater control to the lower empty pocket to open up the space for a double dim unit. I'm sure there is a heater control that will fit in that location as it's there by the factory if you have nav. I can fabricate any dash panel needed, however I don't know the parts I would need to free up the double din space. Any help would be greatly appreciated.
