My current car setup is an Alpine head unit with two inputs, one with a 3.5mm headphone jack output which I currently use to listen to Spotify on my budget-level Android phone. My Alpine deck also has an iPod setting which plugs into the dock of iPod for a more clean sound. The sound is vastly superior to what I hear coming out of the 3.5mm jack.
So I think I'm going to purchase a used iPod touch that can run Spotify(I'm not going to buy an iPhone). My question is whether Spotify would work while using the iPod dock. Because when I plug my standard iPod into the dock, the controls on the iPod become disabled and I can only control it from the stereo head unit controls.
So I'm wondering if anyone has a setup like this, Spotify on an iPod Touch or even iPhone plugged into a car stereo with an iPod dock. Have you encountered any problems?
