Hyundai Repair: Hyundai Tucson OEM 2-din radio readjustment, radio repair shop, radio zones

Question
I'm a Hyundai Tucson (2.7) owner from Russia. Some time ago I got an original Hyundai Tucson 2-din radio/cassete/CD/mp3 unit (model HMP-280JMOL, 2007) from the USA and installed it in my car.
Everything works fine, except the FM radio scans frequencies in an "American way", i.e., with the pitch of 0.2 MHz. In Russia as well as in W.Europe the pitch should be 0.1MHz. So I can tune in on, say, 101.9 and 102.1, but cannot on 102.0. :-(

I need to switch this function over to the European mode - it should be possible through the radio service menu, but I don't know how to access it. They say it might be possible by pressing&holding some (two?) buttons simultaneously. Can you please tell me how exactly I can change FM-radio zones from US to Europe?

Thanks in advance.
Regards,
Eugene

Answer
Hi, Eugene.  I don't have good news.  U.S. radios have no "service menus" that I'm aware of.  To my knowledge, the frequency ranges and increments are preprogrammed into the radio at manufacture and cannot be changed using the radio controls.  Someone in a radio repair shop can probably offer better advice as to what will be necessary to switch your radio over or whether it's even possible.
