. I have a 1991 Dodge W250 Cummins with a Pioneer DEH-p6500 and my phone is an iPhone 11. I tried the IP bus on the aux and it played in my phone for a few seconds then switched to the radio for a few seconds and then back to my phone. So I bought this and it took about 10 minutes to install. So far this works great. Some wiring knowledge is required (power and ground button). The only thing I noticed is that there is now a slight ringing in the speakers. The rest works as it should.
