Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
So I paid for a 2 day subscription for GM online service programming and whilst updating the various modules, I found an option to copy Navi data to SD card
The instructions state you will need a separate SD card which is used for configuring and updating the existing MAP SD card.
I'm pretty sure it worked because I had a MY12 SD card but now have the latest maps
Good. How much for the two day sub?Yep. That's what I have. View attachment 197922
Where can I get more info on the cable and online programming service?It was 50 USD but they have now changed it to 40 USD which gives you access to only 1 VIN for 2 years.
You still need a suitable cable as you can't input the vin and the system needs to get it from the car
A gentleman and a scholar, thank you.Here is where you purchase the online programming
