Is there any way to change the speed of the fast forward? I listen to long lectures(around and hour per file) from a USB stick and the fast forwarding is horribly slow for that...... Is there any way to change the fast forward speed or to get some sort of fast forward bar. Thanks,

I just got a sienna with an AVIC Z130BT installed. When I test drove the car everything seemed to work fine. However since I got it, it hasn't been working. It says the GPS reveiver is disconnected. the mic doesn't seem to work at all. The steering wheel buttons don't control it. Could there be a simple fix for this? My dealer told me before I bought it that he is not warrantying the unit so there isn't much use asking his help. Is it possible that while he was working on the car he did something? Thanks,
