Hi there, I've bought a car with a Pioneer Avic-f9770BT and maps of 2014. I wanted to update them, bought software for it on the Internet but It does not work. Testmode works and updating seems to work also (100% successful) but the maps are still not updated. I've worked with patched IGO-software before with help on forums but the f9770BT is still a secret for me. I've searched the internet for several days! but could not find any helpful information. Can anybody help me?
