I usually upgrade mine using a laptop/a wifi-equipped cell phone, a wireless connection with the car and a downloadable firmware image from Lexus Drivers. And it takes me 2 minutes to download the firmware from Lexus Drivers and 3 minutes to install it on the car.

Since the process is taking good 5 minutes, I do the upgrade once a week only. I wish Lexus make the upgrade a lot easier by linking the car to their servers directly and that should be it. But at the very least it's a lot better than what it used to be: only the dealer could do it, and it cost me couple hundred dollars or even more and it took them 3+ hours to do the job!


I wish what I just said was true! Please Lexus make my dream come true.

Is this OK to take the car with nav override installed to the dealer for nav upgrade?

Thanks

Dragonrt has a good question: What will they say if we have the Nav Override installed and we go in for an update?

HENRY, can you answer with your thoughts?

i have never done nav upgrade, but i have seen people doing that and they weren't questioned. it didn't affect the nav update process
