Okay, it's official. The JVC KD-NX5000 is really lame. Yesterday I wanted to go to a place I'd not been to before, 100 km out of town. I got in the Tesla and started entering the location in the JVC. Once again I marveled at how bad a user interface design it has. Groan. And after many key presses I discover that it doesn't have the target road in its database. Groan. Back into the house and get the Garmin. It's a very hot day so I want to leave the windows open. I toss the Garmin in the trunk. Time to go home. I'm not certain I can back-track the route from memory, and the Garmin is in the trunk; let's try the JVC again. Hit the Menu button. Home is greyed out. It's forgotten where I live! Groan. Enter the address manually. Off we go! Okay now it seems to think I'm driving in a farmer's field somewhere. I think this is my turn coming up... suddenly the icon pops back onto the road, and it tells me to turn right. Do I trust it? What the heck. Finally make it to Highway 17. Now I know where I am. Sign tells me to turn right. JVC tells me to continue straight!!! WTF? Menu. Cancel Guidance. Turn right. Arrive home safely.
