They are still the best options. I have the USA Spec and can confirm that the grounding noise IS kind of annoying, though I usually don't hear it when I have the music going and it doesn't come up when the iPhone is disconnected. The iMIV is the preferred option by most people because apparently there is no grounding noise, it may be slightly easier to install, and it supports displaying text. If you want to do a single-device with Bluetooth and an audio input, I'm sure Parrot has a product that will work (even if you connect your iPhone via bluetooth to steram the audio). Just keep in mind that it will not allow you to control the music via the buttons on the steering wheel.
