  • Communicates even if display device is off
  • Low total cost of ownership
  • Very easy to install


  • No Navigation (coming soon)
  • App feels a bit dated, like TND device
  • WiFi connection to HD 100 limits other WiFi usage on the tablet

The HD 100 is Rand McNally’s low-cost BYOD alternative to their classic TND 765 device. The HD 100 itself is a simple black box that plugs into the vehicle’s diagnostic port. The black box reads engine data and driving status and communicates with an Android or iOS device of your choosing for display. The free app running on your display device looks and feels very much like Rand McNally’s TND 765 interface, so drivers may be somewhat familiar with the layout already.

Unlike most BYOD systems, the HD 100 does not use Bluetooth. Instead it communicates with your display device via WiFi. This can offer a perhaps more reliable and longer-range connection, but it means that if you want to connect your device to any other WiFi networks you will first need to disconnect from the HD 100. This can be annoying, as the HD 100 will only allow communication with Rand McNally’s servers. If you want to also use your device for web browsing, email, etc then you will need to disconnect from the HD 100 and connect to a real WiFi network or to 4G.

Also rare among BYOD systems is the fact that the HD 100 does NOT rely on your phone/tablet for it’s communication. It is able to communicate essential info like GPS location and engine status even if the phone/tablet is turned off! This is a huge perk, and combined with the fact that the HD 100 can be mounted behind the dash without loosing signal makes it probably the most tamper-resistant BYOD option on the market. In fact, since the HD 100 does its own communication, your display device does not even necessarily need a data plan. A simple WiFi-only tablet works just fine, thus saving the significant monthly cost of a cellular data plan.

One of the major drawbacks of the HD 100 app running on your phone/tablet is that it does not yet include Rand McNally’s IntelliRoute GPS Navigation. However, this feature is under construction and may be added to the app by the end of 2016. The addition of Rand McNally’s excellent GPS would make this system a truly top-notch option in the BYOD ELD market.

Pricing on the HD 100, like any BYOD option has some room for variation. The black box itself is affordably priced at $299. If you plan to provide a tablet for your drivers, expect to pay around $150 for a decent WiFi-only Android tablet (such as a Samsung Galaxy Tab). If drivers will use their own cell phones you can save this cost, but remember that the ELD Mandate states that the display device must be mounted to the vehicle where the driver can see it while the vehicle is in motion. The monthly service plans are the same that Rand offers for the TND 765. The Electronic Log only plan is $20/mo. The Basic plan adds messaging and is $30/mo. And the Enterprise plan adds advanced features like engine diagnostics, driver scorecards, critical event reporting and much more for $40/mo.

Installing the HD 100 black box in incredibly simple. If you don’t mind the device and cable being exposed, it can simply be plugged into the diagnostic port and set on the dash. If you want to hide the device behind the dash, that will obviously take more time. Also remember that a mount of some kind will need to be installed for your phone/tablet, which can add another 10-20 minutes.

The HD 100 is a simple BYOD device with some unique capabilities. While it does have some drawbacks to consider, it is a good option to consider for fleets looking for a  reputable brand name at a fairly affordable price point.

    We used the Rand McNally ELDs and they did not work. We had multiple issues where drivers had to revert to paper logs or were not able to transmit the logs to the DOT, forcing our drivers to be cited. Now Rand McNally wants over 60k to get out of a contract they violated by failing to provide good service.

    This company falls very short of expectations the rate of product failure is through the roof. Their ability to get product to us and have it work is ridiculous. What a big mistake it was for our company to choose Rand McNally. Unless you want printed maps and baby books stay away from this outfit…. the lie about training sessions, ship dates and you end up sending more units back than installing ones that work….

      I agree with Steve on every point. They hound you until you sign their contract then you cant get any cooperation. No one answers phones, emails the devices don’t work properly. What a scam. Very frustrated and angry.

    I guess the half a star is the lowest to leave because I would leave a negative if I could. I am having very similar problems. I started off with an iPad and like to never got it to connect to the wifi connection. I was told to change to an android tablet. I did still having this problem. Doesn’t seem quite as often but still do have the problem. Let’s say it does connect through the wifi, then the app doesn’t want to ” log in” even though I am connected. After several attempts and if it finally logs in it is very brief and back off again. I have discovered that when cell signal is weak in the area, I have most of the problems. WHAT EXACTLY IS ONE TO DO WHEN THEY ARE STOPPED BY DOT AND THEY ASK TO SEE YOUR LOG BOOK? ITS COMPLIANT BUT IT WILL BE USELESS THEN BECAUSE IF THEY WERE TO REQUEST COPIES EMAIL/PRINTED I WOULDNT EVEN BE ABLE TO SHOW IT ONSCREEN. WHO WILL PAY THAT FINE? Not happy with this setup.

    The trouble I have is with the App on my tablet. Every time you stop. You have to wait a full minute before you can do ANYTHING with the log. Also, every few hours I have to reboot my tablet as it stops communicating and the App just appears as a useless black screen. Reboot is the fix. I have to do this almost every time i try to change my status. Lastly and most annoying is that once you stop, the App Automatically puts you On Duty!!! This is infuriating as it requires a person with a m PHD in Computer App Stupidity to edit back to Off Duty. The App in my opinion is a Negative 20 stars out of 0 to 5. Yup, Pisses me off that much. To get to the fuel screen, is just not worth it. So I never show fueling as it is a pain beyond words. I have a Galaxy Tab E with the HD100 App.

    We bought 2, to go with our tnd730’s. couldn’t get either one to connect. We spent hours on the phone with Rand McNally support. And in the end I was told both devices were faulty.

    The HD100 is not supposed to have Navigation. That is not what it was designed for. If you want Navigation too, get the TND765.

    The HD100 was designed to save all of Rand customer who already purchased either the TN720 or the TND730 about $300 by offering a unit, that only took care of the EOBR part by mating with their GPS.


    + PROS: Easy install
    - CONS: Need several wiring options because of truck variations
