Sorry but I must speak the facts on this one.
I missed the facts - I did see some opinions though!
I have no problem hearing this or any other Uniden in the car at highway speeds (and occasionally higher )
I run the audio level at max to hear my HP, then it gets somewhat distorted.
Just another nail in why I am done with the HP1.

Sound is great on my unit.... Much better than my 396xt....
