SATNAV software issue. Please help

My Infotainment display on my 2015 Swift SZ3 1.2 Petrol variant shows this error message. Please help me fix this. I have tried different ways. I enquired with dealership and they offered me a free update but they are asking labour charges way more than the cost of replacing the stereo. I guess they dont wanna help me in this issue thats why they quoted me such a huge amount of labour charge just to do a free software update. If anyone had this issue and got it fixed kindly help me out.
