no, it has to be a dealer because they need to have access to GM dealerworld to change and download the new RPO codes

 

So how did that guy in Maine do it? to your car?

 

thats not 100% true, my local garage has it.. they said they have to call gm every month and drop 1200, to buy a new liscence

 

He worked for a dealership.

they purchase the license to GMDealerworld every month? thats nuts... for what purpose? atleast a dealer can tie everything into that from financials to orders to reflashes.

 

i deff hear you on the "thats nuts" part.. but according to the mechanic 1200 each month!!

by the way +1 rep for ya orng.. thank for ya help
