Problem. Tns510 new maps update

[Sam Dragos]

Goodmorning I have a Toyota IQ 2009 with TNS510 system. Recently i bought a new sd card with 2019-2020 maps. My previous sd card maps was 2009 and works fine when i use it, but when i use the new one the system doesnt recognize it and show me the message "Unable to read data. Check if the map SD is correct". Can you help me please?

Hi Sam, welcome to TOC 🙂

From whom or where did you source this new card? I would take it up with them.

Where/from whom did you buy the new SD card? if the problem is with the card (which it sounds like it is) take it up with the supplier.

There are lots of copied/counterfeit/non-Toyota-supplied cards out there ...

Maybe the problem is not the card but the system. I was read that the system needs firmware upgrade cause now read till 4GB capacity sd card. After upgrade will read more than 4GB. Is it true?

Finally the sd card was corrupted. I changed it with new one and works perfect. Thank you for your help. 😃😃😃
