Hi everyone,
I have an AVIC F80TV (made in Brazil), and it suddenly lost GPS signal. Already tried to replace the antenna, upgrade firmware to 1.08, delete and restore the iGO folder in the EXTDATA folder, and even replace the entire EXTDATA folder itself, with no results. My guess is that some files in the internal SD are corrupted. If somebody can give me a hand, i would really appreciate. Thanks!
