    Has anyone thought of installing a Tablet in their MX? I am contemplating the idea of a Samsung Galaxy Tab S3 on Verizon 4G LTE. I would use this mount:

    https://www.amazon.com/gp/product/B00BAQKROW/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

    This visually appealing mount would be placed on the black cover in front of the center arm rest (the cover that hides the USB ports) via double-stick tape (the metal 'stalk' easily unscrews from the black circular base when the black cover needs to be opened). The small circular magnet would attach to the back of the tablet and can be detached via magnet from the stalk. Power is right underneath the black cover at the USB port. While this is a 'switched' power source, I'll go out on a limb that the tablet battery will be sufficient in between charges (or I can always run an always on cable from the ODBII area).

    Why this instead of simply using my phone you ask? Well, in theory at least,this would overcome a few shortcomings and add some great features. First, it has a built-in mobile hot spot for, say, a dash-cam to stream to the cloud. It would have Spotify to connect via Bluetooth. It would have a fast fully capable browser. It would have video. It can run apps. And it would be in a pretty ideal location in relation to the arm rest to allow me to rest my arm and use my right hand to touch the screen. The idea would be to dedicate the tablet for the Tesla and this is a great sized and capable tablet.

    Some drawbacks potentially include that I likely could not connect to Bluetooth simultaneously with my phone. This would in theory cut off seamless phone integration.

    Just a thought. I do intend to get a dash-cam so maybe a traditional hot spot is better.

    I was thinking that you wanted the tablet to be used by your passengers, not for yourself, so:

    - You will have to constantly put it and remove it every time you plan to park your car otherwise it might be stolen.

    - Not really in your line of sight if you put it on your arm set.

    - Do you plan to keep it always on, otherwise you will need to re-sync or reconnect manually your dash cam every time you turn it on.
    (I don't know about the bluetooth dash cam, I have a Blackvue and use Wifi to connect with my tablet)

    - IMO, having a tablet in a car is mostly for navigation, but you have already a 17" screen ?

    - If it's to take notes with a Pen, I'd rather get a 2-in-1 laptop than a tablet,
    because to use the Pen you need to sit in front of a table, or put the tablet on your laps,
    so basically you are doing the same as if you were using a laptop.

    - May be using voice activated features, this tablet could provide additional functionalist
    no found using solely the Tesla display and your Phone?

    Actually, the project would be a dedicated tablet for the car. I suppose it would be mostly for myself. The location I had in mind would be a 'natural' ergonomic fit, i.e., to have arm on armrest, still retain cup-holder functionality, and what would appear to be an easy way to interface with the device. The idea behind it would be to 'complete' the functionality of the main vehicle touchscreen (sorry I know there is a proper acronym but I am new here). My thoughts, for me at least, would be Spotify, RadarScope (best radar app there is for weather geeks), incoming text messages (Verizon Message+ allows for multiple devices to sync SMS and MMS messages), full and fast browser functionality, other apps such as PlugShare, whatever. I also have an ODBII bluetooth gadget that connects to an app to provide real time vehicle diagnostics. I don't know if it works with a Tesla however (or what data it would provide if it did).

    I should mention that any project like this would need to incorporate the various technologies to allow voice interaction, text to voice, hands free / car mode, etc. It would need to complement the Tesla environment and feel like a natural fit, both aesthetically and functionally and safely wise. But I don't want this to devolve into a distracted driving discussion. Per below, it likely will not proceed anyway.

    This project may hit a hard stop. I will not give up Bluetooth connectivity to my phone inasmuch as hands-free operation of my phone is not negotiable. Further research is indicating we cannot have two separate yet simultaneous media and headset Bluetooth connections. This means no music streaming and hands-free phone operations at the same time. That's a big setback for me. And we can't stream over the USB connection - checked that too.

    The project is also making an assumption that the hot spot within the tablet could be enabled permanently (I have unlimited hot-spot data), and that streaming from a dash cam to my phone would actually work well enough to make it worth it. That is separate research I need to look into. The idea of looking out the windows of my parked Tesla via dash cam video to my phone when I am sitting at my desk in real time sounds great in theory, but is that even possible at the level I envision it my mind, i.e., HD quality, no jerky video, etc.

    So that's where I am as I think about this while my car is being built. A final thought here is that theft would not be an issue - that magnet mount allows for easy removal when parked (but does now make me curious as to how long a fully charged tablet would drain battery to stream a dash-cam over the hot-spot when the tablet is in the glove box before it needs to be recharged, etc. So this is another thing to consider, i.e., whether a dedicated wired hot-spot is better, in which case the tablet would not need to include the 4G LTE and would instead connect by wifi to the hotspot).

    Installing a dedicated tablet in a car to provide a multi purpose platform in an interesting concept.
    I noticed Bjørn Nyland on YouTube having a Live Streaming Road Trip channel.
    My dash cam provide such capability, and this is something which could be exploited further
    and in a more flexible way by using a tablet interface.

    Quick update. This project will be proceeding forward! It turns out the Verizon messaging app not only allows simultaneous text messaging with my mobile phone it also allows simultaneous placing and receiving calls from the tablet using my primary phone number. This solves the Bluetooth connection issue because the tablet will establish the primary Bluetooth connection for both audio and hands-free calling.

    I ordered the Galaxy Tab S3 today as well as the aforementioned mounting solution products.
