Congratulations !
As an owner who also has a 100 A old house, let me tell you what I did : I bought and installed a LCS-20 from Clipper Creek (16A on a 20A circuit) in 2014 for my Volt and it works just fine for my Bolt EV too. It does its job and it charges just fine my Bolt EV (even when doing 200 km a day), it is full every morning.

3. We have iPhones and find that the connection to CarPlay is erratic. We use GPS everywhere we go, but sometimes it just doesn't respond. Or it works and then stops working. Even when it works the displayed functions are different.

If you plug the iPhone, do you still have CarPlay available ? If so, use this instead of the wireless CarPlay.

The GPS is based on the phone signal more than CarPlay signal... if you travel in an area where the coverage is mediocre at best... tough luck. Usually the OnStar package "Connected" does the trick in these situations. It looks like the equipment that comes in the Bolt EV is a lot better than an iPhone for getting the signal.
