While the TGP looks like a fine kit, I don’t believe the module they use, unlike the Maestro module, will pull OBD codes (trans temps, coolant temp, check engine, tpms, etc.). If that stuff is important to you, you may want to make sure whatever setup you decide on uses either the Maestro RR or RR2 (if you want to have 3 programmable outputs; ie to control lights thru your head unit).
I asked them about this, and at the time it didn’t do OBD readings.
looking at 8100 unit vs a 10.1" model. The trail grid pro comes out to $948 or $841 without sirius xm adapter, crutchfield with the maestro rr and necessary install items are $1064. Almost a $200 savings with TGP since I dont use sirius xm radio.
What is the main differences between the pac used in the trail grid bundle and the maestro? Do you still need a obd2 dongle (bluetooth) to connect to the head unit ? The sony 8100 is wired car play only and cliff mentioned they've tried a few dongles for wireless but nothing has worked.
locally i can buy an android t10 headunit at $250 , wireless car play , decent fit but read about too many issues. Would like wireless car play, the 9500ES is probably too big of a screen. The bezel is a overkill for it, as for the 8100 has anyone mounted in the lower portion using the OEM brackets to not cover the vents
