Got this msg when I was trying to update the DVD NAV disc that I used to use in my 03 Es300 ( v7.1 )



Anyone can help ??

Some people tried reset battery, and it didn't work.

This is for a GX correct?

Im thinking you cannot use the same disk as you used in your ES--It states right there "Incorrect" NAV disk--Lexus os pretty smart Huh..lol You have to buy one for your Generation Nav system as its different than your ES

i thought gen 2/3 is the same for all Lexus that carry gen 2/3 nav. I know 02-03 ES300 is the same gen with 03-04 GX470.

Then i put back the old one ( ver 1 ) that came w/ the GX and still not working man, never thought tried an updated NAV disk would cause this headache.

i just ordered a 09 NAV DISK from Sewell, let see if that will correct this issue.

thanks Booyah for the respond! like ur screen name, do u have that as ur licence plate also ??

Booyah

Ha..HA no license plate is jusr what they gave me. Try and diconnecting the battery terminal for a few minutes maybe that will reset whatever with the Nav unit--worth a try but you will have to reinitialize your windows and sunroof

I almost did the same thing, but didnt get around to do it, Thankfully. There was a newer Nav disc laying around the dealership I bought my truck at and was going to install it. I have an 04 GX, what disc would be the newest correct disc for my truck? Will it change the graphics and colors like the new Lexus'?

^^^^^^blatantly stolen from some other website!

from what i gather it should work. very strange.

the reason why i posted the 1st quote is that you can find out what version you have by doing that. you can also fix the blutooth volume and a few other interesting things.

EDIT: check the disc for any scratches or see if it has any smudges or fingerprints on it. clean it/resurface it and try it again......this may help or it may do nothing at all. who knows......but hey, it's worth a shot.

I did that for 7 hours and no luck.....same error msg btw, what do you mean by "reinitialize your windows" ? I noticed I cant open my rear windows through the main switch in the driver side after I reconnect the battery. Any idea ?



Well I had is 7.1 in my 03 ES300, which is 2007 version, not much difference beside more street name / location updated and such. But again, I didnt really playing around w/ the old one that long anyway.


Where did you stole that instruction ?? can I have the full URL please ??

I just checked the disc again, I wiped it off w/ clean cloth, no scratches w/ the OLD one, no finger print and still no luck wth lexus computer is so sensitive...

LZMF1

all i did was google "gx470 nav hacks"

i'm pretty sure those instructions are somewhere on these forums

thanks LZMF1!

I just pulled the trigger, bought 2010 DVD Nav and fixed it right away.

what a relief, i thought i have to reset the whole Nav ecu or something.

LZMF1
