my is300 has a problem w/ the navi. sys. l got a good deal on this car that reason. there is no power what so ever to the navi. i've already checked fuses......i really dont wanna pay ridiculous amount of $a Lexus dealership.......so if anyone can help me, i'd really appreciate it, Thanx

If you want it fixed, you're not going to find somewhere cheap. Your best bet would be to take it to the Lexus dealership, as they know what they're doing and are professionals. You could take it to somewhere that sells aftermarket stereos. They might be able to help, but like l said, I'd go with the Lexus dealership.

that can be the manufacturers fault of why it is not working. l have 6 cars at my house and 4 of them are Lexus'. l never had problems with mine.take it back to the dealership and tell them of piece of your mind. Lexus is are awesome cars and are really reliable . its deff. the company is fault!

first off where did u get the car.If from a private seller does it have an aftermarket stereo. if bought from the dealer check to see if the warranty went with it. My guess is u bought it from a private seller due to the fact that all used Lexus vehicles bought from dealer r Certified Pre Owned. Meaning they r all throughly inspected by the tech is & r repaired accordingly. Now if purchased from a private seller then check the milage then take it to dealer & ask if the vehicle is still covered under factory warranty. Also if it has an aftermarket stereo u might check to see if they left it unplugged.
