Hello ... I am Italian, first of all I'm sorry for my English is not perfect, and I wanted to congratulate you for the wonderful site, very helpful and always updated.

I would like to help if possible .. I have the avic F900 and I want to upgrade the software, I have version 2 and I wanted to bring it to 3. From the various topics I see are different versions and do not know what to update and then follow it as a guide, are not as practical as the thing I've ever done, but with a good guide I learn fast Can you help me in update? Thanks in advance.

Don't be afraid to update. First of all make a backup from your F900BT. Read this thread on this forum, viewtopic.php?f=34&t=25817 On SD3 comes your backup from F900BT. The rest is the same. Good luck!!!! I've don it and is perfect.
