 I abhor the "navigation system" in the 2018 Camry!  It RUINS the Toyota experience!  If I had known how bad that system and the Entune 3.0 was, I WOULD NOT HAVE BOUGHT THIS CAR!   First, upon linking to the system, it downloaded almost ONE Gigabit of Data!  I don't use my phone for data, and that cost me another $15 on top of my phone bill!   The Scout GPS system takes FOREVER to load, and will not show a map when you are driving around.  You HAVE to put in a destination!  I tried - really, tried very hard - to learn the system and give it a fair shake, but the hare-brained good-idea fairy that came up with the Entune and Scout GPS should be FIRED!  In my small town, I live a whole 4 miles from the park where the farmers' market is held.  I have a choice - take a two lane state highway, or take the two-lane roads through the city.  I told the scout GPS to rout me home.  The highway is a little longer with a 45mph speed limit.  The through-town is 35mph and shorter.  With the old Toyota system, if I chose to NOT go the way the GPS directed, it would quickly recalculate and map the short route.  NOT the Scout GPS!  That stupidly designed, illogical subroutine tried to route me back to the State Route at *every* left turn I could have possibly made!  It would not stop until I was within a mile of my home!  The route it was recommending was NOT shorter NOR quicker, but it would not give up.  Every second you are in the car, it wants to use your data plan.  Furthermore, it does not want to navigate unless you PLUG IN THE PHONE WITH A WIRE!  What kind of convoluted, half-brained, inconvenience is that?   To enter in your destination takes darned near ten minutes!   To add insult to injury, you are completely out of luck if you are in a rural area, where the mountains cut off cell service regularly!.  You completely lose all navigation.  Unlike Google maps, where you can download a local map to your phone, you simply are lost without help with the Scout GPS. I **ordered** this car specially - I BEGGED the dealer to get me the upgraded built in navigation system, but Toyota DOES NOT OFFER IT ON THE top-of-the-line Camry.  How could you do this to your loyal customer base, Toyota?  Prior to this, I would not even shop for a different make, but all bets are off.  You blew it.Oh, yeah - after three years, you LOSE your subscription and have to pay for Scout!   I would not give two red cents for this mangled excuse for a navigation system.This system is the most illogical, DANGEROUS, instantiation of "Infotainment" I've ever run into - and since I traveled for work and rented a lot of cars, I have a lot to compare it to!First, I had a 2006 Camry Hybrid, then the Avalon 2016.  I compare to those.   If I had a text message come in, I would simply tap in the vicinity of the notification in the center of the screen.  I didn't have to take my eyes off the road.  Tap, and the message is read to me.  No problem.    With the Entune 3.0, the bell tolls, and the message receipt flashes so fast you almost cannot see it.  Then you have to press "Phone", then "messages", then the message in the list.  Yes, you have to take your eyes off the road and traffic to do so!   The hare-brained good-idea fairy engineer and the approving bosses that came up with the Entune 3.0 should be FIRED!In spite of the home screen, you really cannot easily change the mode or channels from the steering wheel as you could in the older models.  For example, in XM, the menu keeps defaulting to the XM "replay" instead of the presets.  Yes, you take your eyes off the road to go to press Audio, select the XM presets, and then the channel you have preset.   Why in God's Name would ANYONE want to drive and try to control their car with a smart phone or a convoluted reverse-logic UNSAFE system like the Entune 3.0?  Just how long should one be comfortable taking their eyes off the road to run down the rabbit hole of menus?  Furthermore, the Entune wants you to download countless apps that are quite happy on your phone, thank you so very much!  Yelp?  Seriously, I do not want people on the road using Yelp for *anything*.  "Hang up and Drive!"Furthermore, all of these attention-grabbing (you know, taking your attention from the road) 'features' cost you in your data plan.  If you are in a big city, you might have it a little easier, but those of us that go Toyota because of its [former] safety and reliability because we drive long distances in desert, rural areas, will not enjoy that luxury.    However, the Camry is a lot sportier, and handles wonderfully.   The radar cruise control is messed up, compared to the 2016 Avalon, because a curve in the road makes the Camry respond with hard braking if there is an adjacent car.  Also, if a car ahead pulls into a right turn lane, the Camry brakes hard as if you were going to run into them.  I don't use the radar cruise control for this reason.  I am really saddened by what Toyota has done.
