B44EB2 - CE 0E
B44EB4 - 00 00
B44EB6 - CE 0E
B44EB8 - 00 00
B44EBA - CE 0E
B44EBC - 00 00
B44EBE - CE 0E
B44EC0 - B0 0E
B44EC2 - 7E 0E
Models number in hex are:
3790 - CE 0E
3770 - BA 0E
3760 - B0 0E
3750 - A6 0E
3710 - 7E 0E
A first I changed value at address B44EB4 to B0 0E (3760). This change gave me ASR. But I haven't checked other features, one notice - there were no 3D buildings in GarminDevice.xml. Next I changed all fields to B0 0E. Then I got 3D buildings, 3D terrain and ASR. I'm not sure about the effects of each field, I haven't done tests with single value value changed, except for first check with ASR.
For ASR to work you need *.srd file and text translation *.glx with ASR section. ASR is using language settings for text. There is only limited set of languages supported and I'm not able to use english with other not supported language. You can download *.srd with WebUpdater.
Edit: do you have mic in 3750?
