I had exactly the same problem one year ago. The dealer allegedly sorted it but I realised the maps are several years out of date. The infotainment book tells you go to the web site. The instructions there do not work. Contacting Suzuki UK help line was wholly negative. they blame Bosch and/or the dealer!!!
Very, very poor service or rather non-service. My previous GPS unit had life time map updates on a £100 satnav!
