Car Head Display C3 Head Up Display Navigation 5"HD Screen HUD OBD2+GPS Dual System HUD Support Map Navigation

I own a 2013 BMW 135is that I've had for 9 years (writing this Jul 2022). Although this car is the closest thing to a real "sports car" that BMW had made since the 1M, there was no Heads Up Display (HUD) option available for it, although by 2013 it was an available option for even the more pedestrian 3-Series BMWs. Anyway, I had been happily driving the car without a HUD, and never having experienced driving with one, I didn't miss not having the feature. Earlier this summer, my wife and I rented a Mazda CX-5 for an extended road trip that took us from Florida to Wyoming. In all, the trip was a little over 6500 miles long. The rental Mazda did have a HUD, and in the almost three weeks driving with it, I apparently became very accustomed to it. After driving my car following our return, I really missed having a HUD. I never thought to look for aftermarket HUDs, but when I did an Amazon search, I was surprised at the number of options available. The configuration of the dashboard in the 1-Series BMW coupes makes placing an LED projection unit on the dashboard for projection onto the windshield impossible. I realized that the only solution was a unit that projected its image onto a self contained screen that could be vertically adjusted. Quite frankly, the reason I chose this XTOBD HUD was because of its size, its self contained projection screen, and its inclusion of both OBD and GPS operation options.Today, I decided to install the unit. Although the manual was a bit difficult to read in part (the Chinese to English translation leaves much to be desired), once I attached the device to my OBD plug so I could see the display, the information in the manual made a lot more sense. As I had previously reasoned, placing the unit on the dashboard above the rounded console was a bit difficult (this is a function of the severity of the roundness of the dashboard above the steering wheel in this particular vehicle than any problem with the unit). However, because of the ability to change the slant angle of the screen, I did manage to find a sweet spot for the display where the image is projected perfectly in my field of vision. The first thing that amazed me was the accuracy of the Amazon item description in describing the stability and (3D) quality of the display. In use, while driving, both of these were outstanding. II am living in south Florida and the summertime sun can get pretty intense here, yet the display remained very readable as it automatically adjusted to varying illumination conditions I encountered while driving. Since it is unlikely that anybody reading this will be normally operating their car in as harsh lighting conditions as is the case here in FL, if you worry about brightness and contrast of the display, DON'T!There a numerous display options allowing you to display many things that the unit can determine from the OBD input. For me, the MPH (easily changed from the Km/H default), and engine RPM are all that is important, although I did have some fun switching the display modes and observing the effects of color on the readability of the display (in all modes the display remained very readable). As far as accuracy goes, the tachometer was spot on (albeit with a bit of delay in responsiveness), and to the best of my ability to determine using the car's cruise control set at varying speed increments, its speed indicator was also very accurate. Since the display is just relaying other information from the OBD unit, my guess is that all of the more esoteric information available in the other display modes would be similarly accurate.One thing that I had considered when I determined that I would need a self-contained projector/screen combination was the degree to which its presence would obstruct or otherwise provide a distraction from my driving field of view. Another thing that immediately impressed me about the unit was that the Plexiglas screen is almost perfectly transparent. Even when looking at the road directly through it, none of my field of vision was distorted. Even though the edges of the display were very noticeable at first, a few minutes into driving, they were quickly adapted to. I haven't driven with it at night, yet, but my guess is that it will be even less obtrusive under those driving conditions.So, if you are considering adding a HUD to your vehicle, I would not discount this XTOBD unit. You have the option of powering it through your car's OBD port or from a car cigarette lighter port (for GPS-only mode), so there is only one cable that needs to be hidden (which I managed to do quite well considering the incredibly tight seams in the BMW dashboard mounts). Mine worked perfectly out of the box, but there are compensation controls in the case that some of the data (e.g. speed) is reported incorrectly. At any rate, I can't imagine you won't be impressed with the operation and functionality of this device, especially at its cost.Note: If anybody reading this review ever determines what the "Spare USB" port on the device does or is for, please respond to this review.

So I have bought two of these and they do not disappoint. I can see the odometer without having to look down at it on the car panel. The app was a bit hard to install and the maps is OK. Wish it would work with google maps and with my phone. Overall I really like it.

My previous vehicle (Mazda CX5) had a HUD unit installed and I really liked having speed and navigation projected onto the windshield. Unfortunately, my new vehicle doesn’t offer it and this was a good option.To say that the instructions are a little difficult to comprehend would be an understatement.I plugged the unit into the OBD plug and was able to set up the basic unit. I couldn’t find any way to change from metric measurement to US. I then plugged in the GPS 12 V adapter and found the appropriate menu(s). Once I realized that the menus for the device are different depending on what source is selected and which power source is used, setup was easy. Speed adjustment can be made throuh the menu.The navigation gave me issues because the unit wouldn’t pair. I deleted and then reloaded the navigation app and the unit paired automatically. Data entry is done on the phone and the phone display is in metric values, however, English values are displayed on the screen.Using the OBD plug, both data and navigation work.The display is good, but like factory installed units, it does washout in bright sun.As mentioned, the phone display is in metric but the display is in American (after setting up in the menu) the only real issue is that the voice commands are in metric and I can't find a way to change in the app.

I haven't mounted the adhesive and driven for any significant time with this unit yet; still need to make sure I like the placement of it, but it's a huge improvement over the $60 POS that I just returned because it lacked any ability to modify the display other than units, didn't work as a HUD, and had a poorly designed mount which couldn't stay attached in 90 degree weather (far from the most severe that something needs to endure in the southwestern USA).This unit has 8-10 different display configurations, and works great as a HUD for monitoring OBD2 data (primarily interested in the coolant temp, especially on road/off road trips in the desert during summer) on my 2010 Toyota Tacoma. I don't know about the GPS features, but I also have no need for them since I have a GPS equipped inclinometer for off-road driving and mounting provisions for a handheld Garmin unit while away from pavement and for my phone when I'm in the city. About the only thing I'm using the gps for on this one is for the time, which I'm not sure I have up on my display (it's available 5 other ways when I'm driving anyway, so I don't particularly care if it's there or not).

Can’t get navigation to work

Not the bbest
