What would I need to purchase, if it can even be done, to upgrade my 4.3 to a 8.3 (none nav.) system?
I don't currently have the satellite or Bluetooth capabilities and neither is really needed. If its an easy addition I wouldn't mind them though :D Navigation isn't needed or really wanted.
What parts do I purchase?
Where would I be able to purchase them?
Would it be easier to go with an aftermarket radio?
I like the stock look and would rather stay with it... But it's easier and cheaper with an aftermarket system I should probably go that route.
