Just purchased a Suzuki Grand Vitara Navigation unit which is a Roadnav S100 C053
It has Igo8 navigation but I have two questions
It says the Igo8 supports Garmin maps, how do I install these?
Also I have a genuine Garmin XT on a micro SD, could I also install XT onto the unit without deleting the Igo8?
Thanks in advance
