How do I measure my battery degradation?

I was trying to listen to YouTube from a video on my phone while I was driving on a road trip. However, I was not getting the audio to work. My phone said it was connected. Is there a way to listen to YouTube from an iphone while driving?

visited a local tire shop in Centreville because I had a flat tire. Since I didn't really know about cars/tires well, the workers didn't seem to really care. I had to replace 3 tires(one in front and 2 rears) and they quoted $1500. I first thought it was ridiculous for 3 tire replacement so I only asked for a single. They quoted $500 including labor fee. Is this reasonable for single tire replacement?

Here is the breakdown

Continental Procontact Rx size 23540R19: ~$440Labor: ~$30

The two rears are also wearing out and need to get em replaced soon. Should I visit this place again?

Can someone briefly explain the simplest way to watch sentry events? I thought I saw an option in the car but can’t find it now.

Do I really need to plug the usb into a computer? That feels so dated. Can I stream the events from my phone?

Had my MYLR7 for a week and went on a cross-state road trip. Got home with lots of bugs and tree gunk on it. Tried a touchless car wash and for the price (and people saying don’t do it) it didn’t do a great job.

So I’m buying into the hype and going self wash. What are some tools/supplies you have purchased that work well? Brushes, scrubbers, sprayers, cleaners?
