Unfortunately, DashBoss is a no-go for me. The literature on Amazon led me to believe it's compatible with Apple. It did not say you must use an Apple as a monitor. This household is not an Apple location! Windows and Android, and the Android belongs to GXPsy. Yep...I sure can see her loaning me her phone for the day so I can play with our cars. :-) I found a used DashHawk that should be delivered soon. It's compatible with all of the GM CANbus in our driveway: 2 Solstice, 1 TBSS, 1GTO, and 1 GMC Sierra. The primary use will be for the CASE Relearn capability. The monitor functions are just extra icing on the cake.
Thank you all for your input. It's appreciated.
