Going from a stock unit to a Pioneer unit, will it still display the vol, track, disc and radio station on instrument cluster?
doubt it! from what ive heard it doesnt!
No, it will not integrate with the dash. I believe theres no way around this., as the blaupunkt speaks directly to the cars brain.
If your wanting to upgrade for sound quality reasons(you want to run an amplifier), i suggest you at least read this
Blaupunkt low-level outputs? You betcha! :D
