Got the deck and a wifi OBDII dongle just waiting for the harness adapter to show up then I'll give it a go.
Also have en route a Pioneer SPH-DA120 which is basically their equivelant to the 007. I know that one will work so it is the backup plan. Only has a 6.2" screen though. I much prefer the alpine but if it can't run dash command that's a deal breaker for me.
I emailed Palmer to see if they had any advise on getting the app to work. Will share the response
