Where do I foind the software to update it?MIB2.5 STD (non-pro) was available both as Discover Media (with nav) and Composition Media (without nav).
In both cases with 8 inch glass display: 5G6919605B
MIB2 STD > MIB2.5 STD upgrade does not require changing the main unit. Just software update. If you have Technisat main unit (software version ending with "T") you need to upgrade to software 03xx or 04xx. New software contains support for APP button on the new display, new menu layout, lot of other changes that are not visible for end user.
Not sure it is. As long as the files aren't uploaded here it should be fine.There are tutorials and file repositories around the web, but I believe posting links here will be against forum rules.
