i have the t505 and rather enjoy it. so far it works best with audio manager at 80-85% volume and the phone at full volume. any louder and you get a hissing or volume fluctuation. However i do wish the broacast signal was a bit louder. this does vary by program though so its not a fault of the t505.
the hands free works awesome, lets everyone in the car talk to grandma at the same time
