Has anyone successfully installed the Mazda iPod integration module in an 08.5 with nav and Sirius? There aren't many options to choose from, so from what I had read I thought this was the best (or only) option. I made sure to get the right harness so I could keep my Sirius and AUX, but after the install, neither of them works

. The dealer who sold me the car swore that it wouldn't work, but I didn't believe them. I tried everything possible and I'm pretty confident it is not user error.
I wouldn't be as upset if I was happy with the way the iPod module worked. I probably wasn't going to continue my Sirius subscription anyway when my 6 months are up because the sound quality is so poor.
What bothers me the most is that if you put it on random (shuffle) and then try to skip a track, random play shuts off. It is such a pain to navigate that unless you're trying to find an artist that starts with A or Z, don't bother.
The install process sucked as well. It came with instructions for the Mazda 6. I also had a copy for the previous version for the 3. The wire colors in the install manual were all wrong. It didn't fit where the instructions indicated, so I had to improvise and had a heck of a time getting all the wires to fit behind the head unit.
Please let me know if anyone else has it working properly. I'd love to be proven wrong.
