I have a 2014 ES350 and I'm wondering what the best way to get crystal clear audio via an iPhone is? Out of the box the options are:

Built-in car bluetooth
USB input and then selecting iPhone
Using an auxiliary cable from the phone to the aux input

From these three, which is the best sounding with the least amount of interference? Are there common aftermarket upgrade options to improve the sound quality (reduces hiss, clicks, pops, etc.)? What about speaker upgrades? I believe the car has the stock sound/speaker package, so approx. how much would I have to spend for a fair upgrade in sound quality?

If you have any experience or recommendations, I'd love to hear them! Thank you!

Why not just try all three for yourself? And if you cannot tell the difference - then why would you care?

Unless original speakers are of very high quality, as a rule, the best return on investment in upgrading an audio system is always on getting better speakers. I remember there is a thread on upgrading stock ES speakers on this board. The OEM speakers are nothing special.
