A little over a week ago I had the LTE upgrade performed on my P85D. A couple of times since then when in parking garages the radio switched down to 3G and stayed using 3G after I got out of the garage despite the fact that there should have been a strong LTE signal (my phone was on LTE) as I was on my normal route to work where I get LTE on a daily basis. I had to reboot the centre screen to get it back to 3G on one instance - on another instance it finally switched back to LTE after about 25 minutes. Has anyone else seen this behavior? Note that I am in Canada and we have had other issues with having trouble locking onto a 3G signal in the past but these appear to have been fixed with V7.
