Thanks for the feedback. I am ready to buy the Avant but a few questions remain. My X5 has the Business CD without NAV and without DSP. I am going to skip the backup camera.

Do I need to add the DSP chipset option?
Do I need the Torque Compatible BT OBD2 option or is there a better option elsewhere?
I already have TPMS monitoring so I assume I do not need to add it to Android?
Any opinions on the iGO GPS mapping?

Thanks!
