Scout GPS won't stay connected to USB for maps 2020

Take it back to the dealer for warranty service.
They will likely blame it on your phone.

Bluetooth is a WIRELESS protocol; it does not work over a cable.
That is a USB connection.

 

I never was interested in the scout GPS, (downloading tertiary apps is not my thing) I have always used apple car play which works like a charm. All my point of interests are stored on my Google Maps anyways. Back to Scout GPS, its supposed to be wireless just like any entune app but most of them has been spotty.

As commented above, Bluetooth is a wireless protocol. You do not need a cable to connect a phone. If you are connecting the phone with USB cable, that maybe the reason Scout is dropping. Try just pairing phone to the car using only Bluetooth. Provided that you have good cell signal, it should not drop the map direction while phone and car is paired.

That being said, yeah, Scout GPS is not the most easy to use nav app. But IMHO, it is still better than built-in nav system that will cost you $200 to update map data. However, while Scout GPS is free for the first 3 (?) years, it cost after free ride expires. Can you imagine when the free period expires, how many of Toyota owners are going to pay to subscribe for this app? I already have stand alone Garmin for my GPS needs.

 

I actually missed that part where it wont be free in the future. From the PDF I linked from Toyota, it looks like it will be free until 2024. I can see the desire for an Optical Disk GPS, you might be in the middle of no where (or middle of somewhere if you are a glass-half-full person) without network and thus no Google Maps , Waze or Scout.
But try removing your phone and then pairing it to the car again, see if that fix it.

 

Yeah, I live in rural area where the cell signal is very patchy at best. If I am in town or on an interstate, I can usually get signal, but just a few miles out of town or off interstate, I can loose the signal. In fact, I don't even have very good signal at home. For that reason, I have pay-as-you-go prepaid sim in my phone. Data connection comes with premium. I usually have the cellular data disabled on my phone. Thus, stand alone Garmin is the best solution for me. It is $100 upfront cost to buy a devise, and map update is free for life-time. I don't need cellular signal to use the Garmin, and it is capable of traffic info and point of interest. It even works by voice command.
