1. GPS Navigation using just the phone in Google Maps and Android auto without the MyLink works as expected.
2. Once I connect the LG5 to MyLink, GPS lock is flaky, navigation is flaky, and not reliable.
3. Based on research from other forums, I made some changes to the setting in the LG5- adjusted battery optimization, set Location to GPS only. In addition to that, I started the Android Auto app and plotted the destination prior to connecting to MyLink. Under this scenario, AA in MyLink work the best with less drop outs and behaving less flaky.

I am hoping that someone has experienced something like this and can isolate the causes.

BTW
1. GPS using OnStar work fine.
2. Still not lear which GPS antenna is being used in AA mode Car vs Phone

So take a look at this. It seems AA uses multiple sources for location depending on the accuracy of each.

I think you need to do a few more tests to isolate it. I suggest:

Try another phone with myLink using the same cable you use now.

Try another cable with your phone.

Try another AA compatible car with your phone.

Something is out of whack. I'm leaning towards the HMI in the car but we need another phone and different cable to have the same issue to prove that.
