I just got a 2006 maxima no nav but has Bose speakers. Their isn't an aux port and the cassette tape has lower quality sound. Any options to get cd quality sound through my phone?

 

I'm new to the forum, but have a clue about audio, so take this for what it's worth...

There's no way to get CD quality audio into your head unit without an aux input (or getting a new head unit - recommended!), BUT, you could get an FM transmitter if you think the factory FM radio sounds good enough. They're cheap enough to justify and also give you Bluetooth and charging.

Here's a random one on Amazon that gets OK ratings (I have no knowledge of it, I'm just linking you to an example):


Hope that helps.
