hi,
I've a 2009 IS 250 with mark levinson + navi + Vaistech Multimedialinq plus. I'm pretty satisfied with the sound quality of my car when i pair the i-pod, but now I planned to buy the 2013 Is 300h.
does anyone know if the quality of the factory usb adapter has reached a good level of quality? or I still need an i-pod integration? if yes which one is the best? thank you in advance

 

The new cars sound good now and the integration adapter won't be needed. But double check with the specific model you're buying.

 

bluetooth and usb connection is pretty good with my iphone.
