I wanted an installed Navigator in my Bolt EV, just like I had in my Chevy Volt, but it is just not offered.
Interestingly enough, I read on these forums much criticism of the concept of paying for this option by people who are not interested in the option of an internal Nav. An opinion rendered useless by their lack of interest in having an internal Nav.
Nevertheless, for two years now, I have encountered these problems:
• Getting in the car with my iPhone in my pocket and while driving wanting to use the Nav.
I then have to work my hand down through my pants pocket that is being held down by my seat belt, so that I can wiggle it out, then take my eyes off the road while I connect the USB cable. Of course, I could pull over and do this more safely, but typically this comes up when I am already driving on the freeway.
• Getting ready to go to sleep and remembering that my iPhone is still in the car and having to go retrieve it from my outdoor detached garage.
The fact of the matter is that I hailed the introduction of Bluetooth as the wireless revolution it was and has become.
I used to connect my iPod by an FM transmitter device from Griffin Technologies, which operated at less than full optimum performance, to be able to hear it through my vehicle's audio system.
Finally radios had an "AUX" jack, but still was clunky and did not support hands free cell usage.
Bluetooth took care of all these problems with the iPhone remaining in my pocket from entering the vehicle, driving and departing the vehicle.
The Bolt EV's insistence on "wired" Apple CarPlay and no internal Nav took all that away for the last two years!
So now I just purchased a refurbished iPhone SE from Apple ($249 - 32Gb; or $299 - 128Gb), without a SIM and use it as a pure WiFi Device.
Setting it up with the same Apple ID as my primary iPhone, turning on Family Sharing, having both iPhones connect to the OnStar WiFi (or alternatively having the WiFi iPhone connected to the WiFi Personal Hotspot of my primary iPhone) now allows me get in and out of my Bolt EV, with my primary iPhone in my pocket at all times and:
• Receive and make telephone calls hands free
• Send and receive iMessages hands free
• Utilize my choice of map (Waze) for an always available Navigator
I am once again a Happy Camper!
The only downside that I can see is that I cannot use CarPlay to make or receive SMS texts that do not work through iMessage. However, I only use these types of texts about 5% of the time (1 out of 20), and if one of these text messages comes in while I am driving, I will hear its tone from my pocket. I will then know to go read and respond to it from my principal iPhone when it is safe.
Next, I am going to research how to jailbreak the iPhone SE so that I can use "car driver" on it which opens up most all of the Apps to Apple CarPlay.
In my case I want to use Plex to be able to view movies on the Bolt EV's display while I am parked. I will then be able to have installed the infotainment upgrade that removes that capability I now have utilizing a separately created flash drive, instead of just on my iPhone's library.
