Relax bro [emoji2] I'll answer some of your questions. It's not an android unit but it's a decent one. The menu's are very quick and screen is good. For fog lights dealership was charging 7500 but they are not oem. You can also get Chinese ones from the market for around 4k.
As for Grande navigation, it costs 68500 and if you exchange your 1.6 unit with it, dealership might charge you difference of 25-30k but it's just an estimate.
