Well close. The Infiniti socket is 16 pins and so is standard ODBII. But this is a 14 to 16 pin adapter. And I thought only Apple uses GD proprietary connectors. The shop manual calls the ODBII scanner the GST (general scanner tool), just to make the manual harder to read I suppose. BTW, if you never did it, for like $20 or so, there are websites that let you download the official manuals. I suppose there are pirated manuals as well, but $20 seems fair considering what cars cost. You get a one day subscription to the service. it is really intended for repair shops.

Poorly design products can kill any battery. Don't they know about low-power/idle/standby modes? Perhaps they do and will be ready to sell you an upgrade with a premium price.
