BTW which OBDII BT reader or app did you eventually use on your CX-5 as you've at least mentioned a couple, like OBDLink, FORScan / Lite, ELM327, or UltraGauge MX? And which one do you recomnmend?
FORScan seemed more than capable and I think a few have already used it for their fluid swap.
I used OBDLink... this is one of their adapters and includes the software
If you go with OBD Fusion you can buy the model year specific add-on for an extra $10. OBD Link basically includes all vehicles though so depending on how many vehicles you plan to use will determine purchase path.
OBD Fusion can be used with any adapter... Link only works with the MX.
