Navigational (global Positioning System) Gps problems of the 2017 Honda Accord

Unknown- my speedometer is off by 5 miles per hour. Think I'm going the correct speed in a school zone and find out it's not reading correctly. Got a device to check it and sure enough it's off. Electrical- this is the second time my gps screen/radio has been replaced due to the fact that I am a realtor and I use this a lot to find the homes my clients want to see. The screen goes dark, the music goes loud, you can't turn it down, screen freezes etc. Or using the gps and I receive a phone call and the screen goes black. So I find it hard to believe it was the radio when the new one is doing the exact same thing. The first time this happened I believe was around Dec 2025 and now it's doing it again. It started again this year but I unfortunately broke my ankle and this car situation was not my top priority. . I have contacted the dealer and plan on bringing it back to them when pete from clear lake Honda gets back from out of town but again, it wasn't a faulty radio and it wasn't a gum wrapper if I have a new radio doing the exact same thing as well as the electrical doing the exact same thing. Electrical- this is the second time my electrical went out. The first time and the second time are the same. Automatic lights don't come on at night and I learned that the hard way. Key fobs don't work to unlock and lock the doors, anything with the electrical system. I was told the first time, OH, it was a gum wrapper in the fuse box area. There has been nobody under the hood of my car so I highly doubt it was a gum wrapper if the same thing is happening again.
