i bought that exact one last saturday night and took it right back to BB on tuesday. utter crap.
static galore
other fm transmitters in other cars would over-power it
the scan function for stations was terrible.
i have another griffin fm transmitter for my 5th gen 80g ipod classic and it works superbly. i might have gotten a dud but i won't know because i'm not dropping another c-note on one.
i also have a belkin fm transmitter that pretty much has all the same functions, noise cancelation, etc. but it's crap too.
we need blue tooth 🙁
