Tool to enable two hidden functions in the Nuvis 3597: TracBack and ecoRoute Standard.
I not deepened the use of Tracback yet, but its function is to record on Travel Planning the last path made in order to return the same way. Maybe it will be useful in off-road and also in road use.


The nuvi 3597 (as Nuvicam and others models with the same navigation system) have as defaults ecoRoute HD. The problem is that to use the feature you must purchase an optional accessory. With ecoRoute Standard may have many features for fuel economy, without the need of the optional accessory.
I made a tool that enables these two functions simultaneously.


Instructions:
- Download the attached zip file and unzip (are two folders: 1_ Record Mods and 2_ Original Restore)


- Copy the contents of 1_Record Mods folder to a blank micro SD card, insert in the GPS and wait for a restart .
- Check in Applications (Home screen) if now appears the TracBack and ecoRoute function


* Restoring the original condition:
- If for some reason you want to restore the original condition (without TracBack and with ecoRoute HD), copy the contents of the 2_Original Restore folder to an empty micro SD, turn on the GPS and wait for it to reboot again.




* surely the TracBack can be enabled on all models of the same operating system family, possibly from 2013 and later models.
Tested in the nuvi 3597 and nuviCam.
