The most practical way to do this is to buy this:

In other words an after market bluetooth to aux port device made by Belken. The only significant disadvantage I see is you don't have the steering wheel buttons to control phone calls. But the cost is relatively low and it should be pretty unobstrusive. I do something like this with my older Garmin nuvis but have this device on my Amazon "wish-list".
