This is a brand new product, it should get you started.
I am trying to interface my CarPC with the DIC on my 07 Pontiac G6 to display the messages.
What do I need to get started from a hardware standpoint to interact with it? (the DIC runs on the single-wire CAN, GMLAN)
Is there a product out there or do I need to build my own PCB?
Awesome, thanks so much!
For those also looking for information, that link led me to an eBay auction of an OBD BT Module modified to talk on the SWCAN network. (link - $100)
Also I found out you can have the folks at OBDPros modify their product to talk over the SWCAN network for an additional $50.... a bit more expensive (about $150 total for the modified BT model) but retains the OBD connectivity as well, unlike the SWCAN-only adapter above.
