griffins were the standard as they were the first, but there are many now. that one looks like it should be all good as the wire from the port to the charger will act as an ariel so i doubt you will get any static.

i had an orginal griffin and a newer one and i have never had static unless it wasnt tuned in.

i have one that is powered from the ipod as then i can use it to play through portable radios and hi fis when im out and about

but if its just for your car that'll be wikid cus it wll charge your pod too.

peace
