This is my third GS300 (but the first hybrid). I have just recently traded in my RX450h for this 2016 GS300h WITH ONLY 14200 (FOURTEEN THOUSAND) miles on the clock. One owner and full Lexus service history from new. Stunning car BUT, my RX450h and the previous GS300 both gave optional routes around traffic congestion (which I had to confirm or cancel). This car doesn't offer any alternative routes, simply saying something like "warning, in one mile, standing traffic". Not a lot of use when approaching it at motorway speeds. Is there something I have to set in the SAT-NAV setup ? I can't see anything obvious and don't want to buy a smartphone just to get that feature on the phone (I only use a phone for hands free calls).
