Debating pulling the trigger on this soon and am confused on the difference between the two wireless connection kits on GRP's website. Is the OBDII option no longer available? Or does the new JB4 Pro Adapter replace it? I definitely want all the active telemetry data the OBDII connection was previously providing if I order one.
(a) has been discontinued
(b) is the expensive one which uses paid app
(c) is the cheaper module which uses the free app
I use (b) so not sure what issues, if any, there are in (c).
