Losing GPS accuracy in hybrid nav disk?
My nav lost its GPS satellite connection recently, so I'll be taking it in for the 2006 ISx50 TSB. I know that I'll lose the override switch, so I was planning on making a backup of my current 5.1 (with override) disk before taking it in, but I want to make sure that the old loading.kwi doesn't have the GPS connection fix in it. Does anyone know?

You have to check your firmware version. 1550 does not. 1600 has the position fix, but retains the override capability. 1650 disables access to the override screen.

1650. That's why it's the TSIB disc. It came out after the bypass instructions were posted here and Lexus decided to remove the capability. My car was built in 06/06, so it came with 1600 firmware which fixed the GPS issue and left the override intact.

You'd need to find a nav disc with the right firmware, then make your own hybrid disc.
Part number is 86271-53020, 464210-0629, DATA ver. 5.1.
I have one, but it's not for sale. I need it.

You should try reloading your disc from the over ride screen. Press the load button to reload the system and the gps tracking should be restored. I did this and it has been working for a few months now.
