We just purchased the 2015 200tNX a month ago. Last week, the radio and maps etc quit working. The back up camera still works. Took it into the Lexus dealer and they claim the radio is bad. What I don’t understand is how navigation is also not working if it’s just the radio. I saw older threads with differing models with similar radio complaints. Any idea on how else to check this or fix it before forking our 4 figures to replace it. Thank you!
