Hi, Was hoping to hear from anyone who has installed an aftermarket Carplay Unit into an E-46. I understand there are some "mechless" Units that will fit without having to preform surgery on the HVAC Tubing. i have an 04 330CI with Harmon Kardon and was told by one installer that any Unit am looking out must have a preamp voltage of at least 4 volts for the Harmon Amplifier to work properly? Would love to hear or see what CarPlay Units other People have gone with.
TIA
Cheers.
