Workaround for navigation override (bypass) for 2007 ISx50

This was tested in a 2006 IS350.

So does the override come back when you reinstall firmware V1550?

sorry if i missed that.

I see it's been asked a couple of times already, but not really answered. Seems like you guys are tap dancing around the answer to this question; maybe because it involves piracy which I understand isn't "legal" on the boards here...

So for those of us that have a 2007 with the 6.1 disc, how do we go about purchasing a 5.1 disc or some other alternative? As far as I know you can't go to Lexus and get a 5.1 disc now that the 6.1's are out. Can someone please clarify how I am to get a copy of this disc so that I can make my over ride disc with the updated maps? (And no I'm not asking where to download it, I clearly asked where I could purchase a disc)

Please PM me or post it clearly enough so that everyone that reads this thread will understand.

Do you still maintain that the only difference is the hack, now that Lexus has issued a TSB to fix "Navigation shows vehicle in wrong location" here: http://www.alldata.com/tsb/Lexus/116...-06/13061.html

I wonder if folks going back to the old firmware are getting the version that susceptible to this problem.

Yes, the only difference we have seen is the hack. None of our navs (V5.1 or V6.1) have ever "gotten lost" like the TSB says. I think most people don't experience the issued mentioned in the TSB. Must be only certain areas/situations.

Anyway, you can always put back in your original V6.1 DVD and go back to stock with the latest (non-override) firmware should you wish...

I actually think there are some changes with the new firmware.

1. I was having the navigation problems as described earlier and this was immediately resolved with the updated firmware. Previously, my GPS was seeing 1-3 satellites but locking on to none of them. With putting in the new disk with the new firmware, the GPS immediately found 9 satellites and locked on to 7 of them. This wouldn't be obvious unless one was having this problem like I was.

2nd, the HVAC ventilate/recirculate/auto setting now persists after turning off the car. Has anyone else noticed this? It always frustrated me that this wouldn't stay at the same setting when turning the car back on. However, with the new firmware, it does keep the setting.

Brovo "technique"; I knew someone here could do it. After some misteps I am finally getting provicient using the override. It is no longer more than a minor inconvenience.

Wish I had both discs... they swapped my original after I was having location problems.

Can't wait to see what v7.1 (or whatever the update will be called) will do. Will we have to wait for the 2008's to arrive, or is there a possibilty that newer editions of the '07 will have an updated Nav version?

Well, don't confuse the DVD version (V5.1, V6.1) with the NAV version (Gen 3, Gen 4, Gen 5)

The new DVD version, V7.1 or whatever, will just be new map data, for the most part...

The big change will be when the Gen 6 navigation unit comes out. I wonder what's in the LS460. I am pretty sure it uses a hard drive but I don't know if it's GEN 5 nav or not...

Great work.

I have a 2007 IS250 with V6.1 Nav DVD, 1650 Firmware. I also own a 2004 Lexus RX330 with V4.1 Nav DVD. Will the V4.1 "loading.kwi" file work as my firmware file with the V6.1 maps?

[sickntired]

I believe the LS 460 has a variant of Eclipse's AVN7000 which also has a hard drive. It is probably a variant of the Gen 5 system.

Malon015: won't work unfortunately. I believe your RX 330 is Gen 3 and you would need a disk from another Gen 2-3 system (I believe these were compatible).

I believe your RX has a Gen 3 or 4 nav, not a Gen 5.

It might "work", but not worth trying, as it will probably barely be functional... You gotta stay with GEN 5 firmware... So V5.1 is your only option...

wilol a version 4.2 will work or only ver 5.1?
