I"m not sure what Nav system it uses, but looks good to me and works good as well. Easy to install.. Just plug and play since they provide all the wiring with clips. I did it by myself. Only issue this has is, if a USB flash drive is connected to its USB output, when you listen to the radio, it suddenly plays the USB. It's not a big issue. I just remove the flash drive when i want to listen to the radio.Looks nice!
What NAV does it use?
I haven't tried with the iPod. I think i coudn't use the stock USB outlet and play it after i installed this. Btw, in this system even if you remove the USB and plug it again, it continues from where it stoped last..Any idea if the USB issue also happens if you're running something like an iPod? I just leave an iPod nano hooked up to the USB in the car all the time with the generic stock head unit and it seems to work fine.
