With Alcatel 997D (MT6577) there's no issues after the upgrade to 4.1.1. With 4.0.4 I used the Garmin Streetpilot 1.49 with no issues at all.

I copied the Garmin folder of 700MB's to the sdcard, then installed the 2.22 apk (25 MB). Copied the two library files as mentioned to first post, changing the permissions for the second one and the application is running perfectly. My device is rooted.
