Exclamation grom audio usb 2 not working


I bought a bmw e46 316 ti, 4 week ago.

So i desided to get a grom audio ipod kit (GROM-USB2P)

›esterday i got it in the mail and i instald it, so im happy until i turnt it on.
I cant get it to work.

My radio keeps saying no cd.

radio model: cd 53 (e46)
Type :65.12-6 919 072

this is how i connected the Grom kit:

power -> (9) 12V Dir ( i have power on the grom box)
signal -> (7)Ibus
grd -> 15(ground)
10 pin conecter ->bus A

I connected the directly in the back of the radio, and not throw a cd changer(don't have a cd changer and there is no pre-wiring)

Can anybody help me ???

I have one that connects to the cd changer wiring. I was getting the same thing "no cd". Sometimes it would work for a few minutes but mostly would display "no cd". After trying everything I could think of I contacted Grom and they sent out a replacement and it worked perfectly. They were slow to respond but did make it right in the end. I would contact them and be persistent.

Thumbs Up

So today i was giving it another try to install the grow box.

And guess what i got it to work.

After checking every cable and connectionit still didn't work.
So i was thinking to give it one last shot.
I was going to give it an firmware update via the usb poort, and it work.
