Garmin Express 188.8.131.52 Loads NA2015.10 to device will not load to computer. Doesn't work with GarminMapUpdater 3.3.3 or GarminLifetime.exe 2.0.12 the old standbys. In the Program Data/Garmin/Core Update Service it is missing the CNNANT2015_10update.msi installer file. It does download then goes to configuring then to install and errors off and tells you to try again or contact support--Which I did. The files are in the Program Data Garmin Core Update Service Folder but no Installer package there as in the other MAP-EU-2014-40 or the old Map-NA-2014-40. If this helps any.
