Well I decided to give this a shot. I ordered my arduino, lcd, and all the various parts. I'm using the iso interface. I've gotten everything wired up and I tested it today in my vehicle(99.5 VW Jetta). All I managed to get is the Init failed screen. I've tried for Iso 14230 slow/fast as well as 9141. I checked the plug in my car as well as searched the web to confirm that my car does indeed use the iso protocol. I have also checked all my wiring and everything seems to be correctly wired.

I'm a bit of an electronics noob and I would like to know where I should go from here. What steps should I take next, etc? Thanks.
