U can run USB and Ipod. I was running the USB and the AUX cable. Was working fine. Just cant run 3. I didnt have an ipod, so i used USB. I stopped using the USB because it didnt display the songs that were playing, just track number on screen. I wanted to see the songs that were playing. So USB isnt a problem. I also didnt need to disconnect between devices, Just select either device (USB, AUX), and it would play from where it left off. Yeah all that plastic needs to come off, But that's easier than the air vent. u dont need tools to remove it. Shift gear into Neutral, (can unscrew gear knob if u want) lift up centre consol box lid pull up plastic trim from the Box end, 2 clips on either side of centre consol, neat sat/nat end. disconnect 3 wiring connectors and its out. Air vent: lift up with plastic/screwdriver slightly then pull out towards you. all held in with just clips disconnect 2 wiring connectors 2 10mm bolts at top (air vent end) 2 10mm bolts at bottom (consol trim end) Can be a little tricky, try not to drop the bolts from bottom end. sat/nav unit will pull out. dont need to remove fully Just pull out enough to see the plugs on back. (if u take off gear knob, put a rag on top, as the sat/nav unit might get scratched when u pull off) Find the right plug at the back of unit. (only fits in 1) will prob have to disconnect a dark grey plug out first. fit the y wiring harness (TOY) to dark grey plug, and other end into unit. then plug your GROM box in. connect your cables (usb, ipod, aux) and away u go Good Luck with it all
