When I had the E70 loaner, the RDS on the radio annoyed the hell out of me! I want it to display the name and artist of the song, but it really screws up the preset station IDs. When I first set the RDS to "on," a Kenny Chesney song was playing on the one station, so the station ID is showing as "KENNY" and not WPOC, like it should. WIYY is showing as "MICKEY" because that is part of the name of the morning show.

I had an E70 loaner last week and I found the fix for this issue.
If you program the radio presets with RDS turned off, it will display the station information - normally their call letters - once RDS it turned on. It's not 100% correct (one station showed as LOCAL-44 instead of HOT99.5), but it was a BIG improvement over the artist names or song titles that would show when the presets are programmed with RDS turned on.
Gresch - Thank you for passing this along to me.
