I just installed the Quidzel solution last night. Sounds great, shows up as AUX 1 on the headunit. Easy install. You need the PAC 3.5mm noise filter to go along with it however. It's another $8 or so. Doesn't detract from the signal quality in any perceptible way, yet mitigates the hum one would experience if charging the source whilst also playing back from said source.
