, SD card reader worked good, DVD player doesn't work, the radio displays a no device notice when you try to put a dvd or cd, if you press too many times the steering wheels the radio would freeze

I do miss google navigation with live traffic, but this works just fine.

I have had the otto navi for 3 weeks in my 07 Camry works great has a few bugs but overall for the price its great
