Then I tried it on my second one but went straight for 7.1 when it was available. After I had flashed it, and copied the xml files, none of the features were enabled and all the xml files were still in the \Garmin folder. So I have a feeling it has something to do with the newer firmware.

I then used the SD card method to enable the features but the only feature that didn't appear was the Video Player. So I reflashed my 3760 back to 37xx firmware, and redid the process again first starting with 34xx 4.80 firmware, then copying the xml files to \Garmin and then all the features were enabled and xml files no longer there. Then upgraded using WebUpdater to 7.10.
Oh, I never thought of going back to FW 4.80 since my nuvi was already in 6.xx and you're right on after updating to v7.10, everything screw up. I can't enable nor disable on 7.10. Something must be blocking the file. Maybe Noeman's Moderators might able to answer that. There's a lot more problems on 7.10 so I return the device for an exchange for a new 3490 since i only had it less than 3wks.

OP: 1) Since 3490 already enabled these, see picture, do I need to enable again or no need too.

2) Also, will enabling VideoPlayback, TrafficEula, CustomMainMenu, MP3 Player, TTS Phonetics, & TrafficEula work on nuvi 3450? I know that bluetooth & voice command will not work unless you soldered for voice command.

3) what is TTS Phonetics, CustomMainMenu, & TrafficEula use for? I guess TrafficEula you need a GTM60 to work? Is TTS Phonetics for ASR (voice command)? if so no need to enable.
