Let me start by saying that I do not think this is an issue with V1D, it is an IOS issue, and it also happens with Waze. Has anyone else had a problem with either of these apps ceasing to work while in the background? It occasionally happens on my 5S and X, both are running IOS 12, but it also happened with IOS 11. Yesterday I'm driving along and noticed my V1 wasn't muting to K-band when it should, and I needed to restart the app and it had to reconnect to the dongle. Today using Waze it stopped giving me directions and I had to reload the app. I started noticing this with Waze around the time they released IOS 11. It seems to only happen with apps which utilize the GPS and only while in the background. Spotify and Pandora never close while I'm streaming music in the car. I have the location service permissions for V1D set to ALWAYS and even tried enabling Background App Refresh, which didn't work. Anyone else experience this?

I would suspect GPS accuracy issues.

Both apps depend on it.

V1Driver will stop muting if GPS accuracy is poor.

You can try bumping up the accuracy threshold in V1Driver.

Make sure everything is On in system settings for each app. And background processing is allowed.

You can save a recording on V1Driver and play it back to see how accurate V1Driver was when it failed to mute.

Wierd things can cause GPS accuracy to go south. From interference, noisy power.

I would look there first.

Hmm, I'll try that, but like I said, it also happens with Waze. Maybe I have some sorta interference in my car, as you stated. I'll have to pay attention and see if it also happens when I'm in other vehicles. Thx..

Waze depends on GPS signal as well. I have a mountain biking navigation app on my iPhone 8 that freaks out when GPS reception gets weak, even sometimes corrupting data when I try to save my ride for future use.

There are lots of things that can degrade GPS reception, including how many satellites are overhead and how they are arranged in the sky (low on the horizon makes things a lot tougher for your receiver), trees, tall buildings, car roofs, and as mswlogo said, "dirty" 12v power and interference from other devices and car components.

There's nothing you can do about the satellites except wait, but you can move your phone around to see if the other factors are causing problems.
