You cannot replace the physical memory within the TRX7 hardware.
However, you CAN add a microSD card to expand the memory on the TRX7 for videos and pictures (Note you will have to manually move those pictures to the SDcard). With the latest softare version you can now save your DigitalGlobe/Satellite imager to your micros SD card as well in order to save memory in your device. A Class 10 microSD cards up to 32GB are currently compatible with the TRX7 for storing files, including photos and music.
- DO NOT use any microSD cards larger than 32GB. Using cards that are larger than 32GB may result in data loss.
