well after taking a drive...still nothing. I noticed tho that a few seconds after i put the vehicle in drive and take off...the installation position setting went from "OK" to "excessive vibration", then just after i come to a stop it goes back to "OK". I also noticed that when it goes to "excessive vibration" i have no satellites, but when i put it in park and shut the vehicle off i get two of them, but no more than that. I ended up pullling the whole head unit out of the dash and noticed that the "car speed signal input" wire isn't hooked up...does it need to be cause the previous owner r
