Huawei Ascend Y300 - Phone
800x480 - Rooted - New Zealand

I can confirm full operation with Garmin and homemade street and topo maps. No issues after a couple of days testing.

Unlike shunjo2001 at post #287 that version did not work for me. My SD card is recognised as /Storage/sdcard0/

My method.
Post #1 "need root version"
Post #2 "/ Storage/sdcard0/Garmin"


Well done developers.
