GPS not working properly

anyone had problems with their gps not showing your proper location. I did get window tinting done but with a film that is not suppose to interfere. Also got a clean air sticker I installed on my windshield up by the rearview mirror. This lets you drive in the hov lanes in UT with only one person in the car. Couple of questions, where is the gps antenna and how can I check the signal strength? couldn't find it in the manual. Thx in advance for any help. Also, the car is 3 months old and this problem just started recently.

 

I see that you can do a manual calibration. Is there a feature somewhere that I can let the GPS find where I am at on it's own? I have tried the reset method that says to hold the radio power button down for 5 seconds.

 

Mine couldn't find exactly where I was. It had me in the right city but miles off. Some how something went awry in the last week. Went back to do a manual calibration today. This time I parked at a major intersection, zoomed into that location, then put in the direction the car was facing. Putting in the direction you are facing is very important. Last night I did not do that porperly. Seems to be working now. Will follow-up if any other problems. Thanks for the replies.

 

Your right, didn't think about that. It would be impossible to move your gps location. thanks for the info

 

Been in the car last 10 minutes and don't have an option button on the screen or beside the screen. I think I have been thru all the screens possilbe. You would think that working with computers for 30 years this would be a piece of cake.
My car is the v5 adv package. Anyone that can give me step by step instructions to see if I am getting a good GPS signal would be great. I have tried with windows down also. by the way, may cell phone gets a great gps signal windows down or up while in the car. Oh, by the way, on the way home on the freeway no obstructions, the gps was still lost.
Another footnote, in the manual it says the letters GPS in the upper left corner under the foot accuracy should light up. They are grayed out no matter what I do. That means no GPS signal.
Guess it's off the to dealership tomorrow. PS: anyway to accidentally turn off the GPS?

 

Update to above problem. Dropped off the car at the dealer this morning and picked it up this afternoon. They couldn't get a GPS signal also. They deemed the GPS unit as bad. Said they will contact me when they get a new unit in from Toyota. Could be a week or two. Not to pleased about the wait time. Sort of glad it wasn't something simple that I missed because of all my past computer experience.

 

New update. A new head unit arrived 2 days ago. They installed it and now the problem is even worse. My car is in Utah and the GPS put me in DC. The tech is going crazy. Can't figure it out. Even though his test equip. told him he was getting sat. reception, Toyota told him to order a new antenna and try that. They may know something tomorrow. Sure don't like them tearing my new car apart trying to troubleshoot. They said I am the first to have this problem and the system is so new they really don't know what they are doing and learning on my car. YIKES!

 

Yes, that was one of the first things I checked when I started having this problem.

 

Well here is the latest and I hope the last update regarding my GPS Nav system problem. After a week in the shop and swapping out parts it turns out it was the GPS antenna which is located in front of the steering wheel under the dash. The reason it took so long is because they would oder a part try it, then move on the another part that had to be ordered and try again. The did supply me with a loaner car and did not charge for the car or the gas I used. I was patient with them and they thanked me for it. So if you have a Prius v with nav that the gps letters in the upper left corner of the screen just under the number of feet the zoom is set to and the are greyed out, then you have a bad or no gps signal. That's my story and I'm sticking to it.
