I just purchased a 2003 Accord EX 6cy AT and on acceleration there is a high pitch sound thru the radio. When I turn radio off it goes away. Any ideas? this is very annoying

Do you have an AUX adapter installed?

I have the same issue. Is this due to a wire not being properly grounded?
I don't have any sort of aux adapter installed.
