I have the Navigator version of the new Chevy Trailblazer, coming with a bundled GPS navigation system. The unit is in Thai only and I don't have a clue of the brand or the way to get an English version (if it exists)

Of course the Chevrolet Krabi or Suratthani, although kind, were not of any help and they don't have a clue about the system.

Still waiting an answer from Chevrolet to my email.

Anybody has any more info?

It could be the same as in the Toyota Fortuner they supplied Thai on SD card it took another month to get a English version from them. What I have done now a guy sent me a unlocked SD with Tsm 11 and it work's on the Toyota unit and my Nuvi. If you want a copy I could put on a SD card and send to you.

Thank you John, but the GPS in the Chevrolet is different from the Garmin, so I don't know if your map can work there.

Yes the one in the Fortuner is not Garmin and it works. Try to download a unlocked version from the web and put a SD card and test on your unit.

ok, I'll try. I know where to check. Thank you again

Today an English speaking employed from Chevrolet headquarter (tel.1734) callmeafter a requiring email I've send to Chevrolet a couple of days ago. He said me to go to a main Chevrolet dealer (in my case in Krabi) and they will download and upgrade the Navigator with the English translation. In the same occasion will be available also the English language manual.

2 thumbs up for Chevrolet and their efficient after-sale service
