The number of users viewing a forum is NOT a basis for choosing what forum to post in. Post in the appropriate forum.
Granted, your post fell into the appropriate bucket. Understand that number of viewers isn't supposed to be a factor in wich forum you post in. That's how spammers decide where to throw their crap.
First of all, I am sorry you orderd from mp3playerstore. They have less than stellar service and support for their products, which are also generally regarded as crap. I HIGHLY suggest you check out their rating on http://resellerratings.com It will open your eyes, I'm certain.
Second, this forum is all about vehicle computer installations. You would have better luck contacting Innovatek for more information (good luck!) or perhaps a car audio specific forum.
