I'm not sure if this is in the correct place, so apologies in advance if it's not.

Which system does the 21 plate Suzuki Vitara satnav use ie: Tomtom, Garmin? or would connecting my phone & using Goggle maps be a better option?
If its Tomtom/Garmin is the satnav any good with regards to using the best route, recalculating, traffic jam/accident avoidance.

Thanks in advance & again, sorry if I have put this post in the wrong place.

Not sure which system it is but if you don't like you can use your phone -

SZ-T and SZ5 trim levels get a more sophisticated touchscreen infotainment system with integrated sat-nav. You also get Smartphone Link, which lets you mirror your smartphone on to the screen with Apple CarPlay/Android Auto.

Google Maps. The granddaddy of GPS navigation options for almost any type of transportation. ...
Waze. This app stands apart due to its crowd-sourced traffic information. ...
