I see that the V6.21 update must include world base charts, 3D data and satellite photos. Are all these files required to remain on the unit? I've always deleted all unnecessary data from my TZT2 and TZT to reduce the system overhead. Similarly, I'd like to do the same with the V6.21 update. Once a complete V6.21 install is completed, can I then go through and delete all the data (charts, 3D and photos) that I'll never use?
Or, if there are data files that must remain, does the software account for this and not allow them to be deleted?
Thank you.
