2002 540i, need iPod and Bluetooth
I love my E 39 but I want the new dashboard technology. Local car stereo guy suggests Pioneer Avic Z140. Nav system with 7 inch touchscreen, replaces my radio and nav system.
Perhaps it is time for a new 550 but I think I prefer old 540.
I wonder if the forum has suggestions on this kind of retrofit. Thanks in advance for advice and help.
