The 2.169 are only a AF fix from the 2.116
HB say update alle units to 2.169, the 2.120 have more issues!
In september 2012 coming a new update!
here the mail from the HB software-guru
Remove 2.120 – that software caused new issues that made Chrysler pull it from production. New software will be available shortly that fixes all of those issues originally corrected in 2.120… timing should be in September 2012.
OK to update all 2.116 and 2.120 radios to 2.169.
