I've read some Grom topics and some guys say that it works just fine on the bottom loaders and some had problems with it. That's what I'm affraid of :/ As I know my luck I'll get the kit, spend an evening to mount it and than it will not work.
SHAHZ do you have 13901 or 13902 head unit? I have a 13902 and read that it doesn't work for some.
P.S. I emailed grom, sent them photo of my cd unit and asked if they can confirm that it will work. Hope they can cause i'm fed up with fixing the changer over and over again and having to listen to FM :/
