Really cool mod, seems too good to be true so there are obviously a number of trade-offs. I have the base business CD radio and have a few questions:

• Will the info display in the instrument pod still work? If so, how do you reset MPG, select trips, etc.

• Will the AMP in the aftermarket radio power the speaker or will it use the factory amp?

• I seen a few references to boot times. Does the unit cold boot every time you turn the car off / on or does it go to sleep and wake up quickly?

• How is the OS upgraded? I seen a few references to new ROMs - can these units be upgraded just VIA USB or over the air?

• I've seen a few reviews that said the glare can be bad with the OEM looking units - would this unit: https://goo.gl/Xi4TLw be any better since the screen is more vertical? I wish it still had some hard buttons.

Might be a good spring / summer project - so I have a bit of time for 8.X to mature.
