sat nav doesnt know where it is

[wato]

Anyone else have this problem? I have a 2007 IS250, If i dont push the 'MAP' button then tap 'i agree' to show the map for more than a day or so the car gets lost and shows my location generally no where near where i am, and i have to go through the whole process of calibration etc. It seems its forgetting or losing its memory unless its turned on. Many thanks, bob

I guess updating the firmware may help. It's common problem with alot of nav systems, not just Lexus. What version of maps are you running?

Hello 007, i think I'm v18, so how do i update the firmware? Thanks

Pretty much nav updates also come with firmware updates so updating to v19+ should help.

I don't remember v18 maps having that problem, so it's the firmware. You can contact a Lexus dealer to see whether they'lol update the firmware. Who knows, it might be free even if you're out of warranty and don't want to get your car serviced there.
