Screwed up my cam bus.

Screwed up my cam bus. Did not recognize older system. Windows, locks and other things stop working. The worst thing about this is Atoto locks out other OBD2 from working with theirs.

Doesn’t work with my Lincoln

The first gen Lincoln ls uses ford J1850 PWM the obd2 reader doesn’t seem to be compatible with that so it will not connect kinda sucks this was the whole reason I bought this radio but it seems yall don’t make one compatible with my ls other brands do so I’ll be buying one from veepeak love my radio an reverse cam tho sad on the obd2 mini but it is compatible with my truck so I’ll most likely be buying another radio for that so I’ll give 3 stars sadly doesn’t work how I want but does work so can’t complain to much other than I do have to put $160 more into this now yall should give a dude a discount for my next purchase!?
