I still use the LR4's satnav when I need to go to a specific address or memory point, habit I guess... But the directions seem to be quite accurate as long as I turn off TMC, plus I've figured out a way to speed up voice entry - which was otherwise excruciatingly slow thanks to that chatty lady asking you to confirm every word and number you just said and then "Are you finished or do you want to change something?", and "Do you really want to go to there or should we cancel and start all over again?"... Shut up already and give me the friggin' directions! I like the clear turn info that pop up on the touchscreen and the instrument cluster better than looking at my smartphone (I use a spring loaded holder attached to the CD slot for the phone, BTW.)
If I need to go to a business I don't know the specific address of, or I am running late and need some smart rerouting in traffic, I use Waze or Google on my cell. "Navigate to my closest Home Depot"... Can you imagine figuring that one out with the built-in system? Home Depot may close by the time you are done entering the address.
Perhaps the upcoming 2018 Discovery 5 will surprise us, but I think as Land Rover owners we should just learn to live with disappointment when it comes to infotainment technology and related user interface. Even their latest models are already outdated and outclassed by most other manufacturers at the very moment they hit the showroom floor.
