3GP:0 error code 160, GEMMI_nav:0 error code 141, 146

You may see those errors during firmware or maps update, why they are? If you see them you probably do not read properly our tutorials

in 99% you have copied files on to SDCARD by using MacOS system, this can brick your MMI unit, we have clearly mention to use Windows based computer to download and copy the files on to SDCARD. MacOS is creating lots of hidden files which are not visible to you, but MMI can see them and they are making it confused which files to use. 

But if you prepared SDCARD on windows and still got one of these errors, then your sdcard is probably damaged.. try to format again and remember to use FAT32, download & unpack again files and copy on to SDCARD – if still fail, use different sdcard.
