The downsides of putting in android infotainment programs in your automotive

I used my Mahindra Scorpio S4 and Maruti Suzuki Swift Zxi Kind 2 for my experiments on android head models.

BHPian yogeshnaik just lately shared this with different lovers.

This evaluate is predicated alone utilization, analysis, observations that I’ve accomplished on few android automotive audio head models. I had labored on design and improvement of OEM and aftermarket Automobile Audio Items for nearly two years and this enthusiasm made me to discover new applied sciences on Audio Head Items. I used Mahindra Scorpio S4 and Maruti Suzuki Swift Zxi Kind 2 for my experiments on android head models.

Android Audio Head Items are rising available in the market as reputation of the Working System is already seen in Android telephones. Its Linux kernel benefit and the app repository are a boon for its success.

When you think about a brand new expertise in infotainment system in your automobile, one must be utmost cautious in deciding on a system as a result of this occurs to be an integral a part of your automobile and might result in sure irregularities and malfunctioning of different linked modules. For the reason that automobile is a folks service, security of occupants and others on the roads must be thought-about, deciding on a correct time-tested Audio Head Unit (AHU) will wade away the chance, one thing new expertise on {hardware} or software program can result in unknown occasions.

In case you have an OEM and need to change a system nonetheless for exploring new options or simply for enjoyable, my main advice is to not tamper the OEM until you might be outfitted with correct info on the system, its execs & cons the unwanted side effects and what are the options that may hamper the conventional operations of the vehicular platform. If the audio high quality supplied by OEM AHU is significantly good then sticking to OEM programs could have a peaceable enterprise between the automobile and the driving force, it’s because the OEM AHUs are nicely examined with all the required take a look at circumstances in all climate, street situations, speeds, energy consumption and cargo on the battery. In case your AHU is linked to the CAN bus, then this technique turns into an integral a part of the vehicular platform and shouldn’t be tempered until beneficial by OEM. It’s because the timings on the CAN bus transmission and reception are nicely calculated and matched within the Bodily Layer for the OEM AHU and if any offset in timings within the aftermarket AHU can result in misinformation or a bus lock-up ensuing to malfunction of different modules like Physique Management Modules (BCM) and many others. A automobile electrical infotainment system is a cluster of useful modules like BCM, ECU, ABS+EBD, Airbags linked in a community, so any international physique like a brand new untested AHU could or could not gel with the prevailing modules.

Final however not the least, sticking to the OEM Audio Head Unit is having a peaceable method as a result of OEMs are accountable and chargeable for their deliverables and consumer shouldn’t be.

Disclaimer: Any un-approved modifications on the automobile can utterly void or restrict the guarantee and compromise security. Please make sure the authorized issues earlier than any modifications.

Parameters to think about an Aftermarket AHU:

  • If OEM doesn’t present an Audio System.

  • In case your automobile guarantee shouldn’t be voided or guarantee is over making certain it wont hamper the first features of the automobile.
  • If bodily buttons are current. Contact-screen programs are harmful, it is advisable take off your eyes to function on it.
  • In case you have religion within the installers. Wants knowledgeable installer who makes use of pin to pin correct coupler OEM adapters, make sure that no wires are minimize.
  • In case you are an fanatic and need to do some R & D.

Execs of Android Audio system:

  • Provides a enjoyable issue for navigation.
  • It may be used as a Carputer (Automobile pc), Web Looking on the go or any computation process you are able to do.
  • Some have in-build 4G-LTE SIM enabled the place you’ll be able to insert a SIM card for flawless web connectivity and downloading of maps for navigation.
  • Characteristic wealthy, you’ll be able to add any utility from the Android Play retailer.
  • Good for expedition and for individuals who prefer to have all info on one display screen.
  • Sure GPS based mostly apps are useful in detecting the precise velocity of the automobile.
  • Not all however some Android AHUs have higher Audio DACs, nearly all Audio CODECs like MP3, MP4, AAC, FLAC (lossless) and a bunch of Video CODECs (for co-passengers, not for driver).
  • WiFi, Bluetooth connectivity and AUX-In for exterior Audio Enter.
  • Appear and feel of the dashboard is enhanced. Consider me, you get a premium really feel too.
  • Combine Learn-View Digicam to the AHU enhances security.
  • Since Android is a heavy working system, Android Go is used as a light-weight OS.

  • Android & iPhones will be linked utilizing Bluetooth, each works flawlessly.

Cons of Android Audio system:

  • A lot of the Android Methods include contact interface and no bodily knobs or buttons (besides few), operations like altering tracks, shopping folders for audio observe, one wants to remove your eyes from the sight of the street and take a look at the display screen to function on contact display screen which is harmful. I discovered this as a priority myself.
  • Alternatively, a steering wheel distant minimizes this concern to a sure extent.

It occurred to be a priority to me after I go away my automobile for service or hand over at Valet Parking.

Nonetheless, you’ll be able to set up sure locking apps, however nonetheless there are loopholes and can’t be in contrast with the OEM sort of safety.

Alternatively, create one other Google account just for this objective as a Workaround making certain no emails are setup.

Some android programs are designed to enter standby mode solely, not into utterly shut down mode when ignition secret’s eliminated. So, for those who park the automobile for an extended time say for every week or a two, the battery will get drained. My findings on this with a video are mentioned intimately on this evaluate.

How Secure is Android AHU:

The {Hardware} is designed in the same method as that of different AHUs, however some are slim, mild weight with no compromise on audio high quality. There are specific imports accomplished from North Japanese international locations, that are promisingly providing at a reasonably lower cost that lures a purchaser. I’ve tried from entry degree to excessive finish Android AHUs. Some Android AHUs are having low cost materials, for those who observe keenly, the mounting screw grooves with threads get ruptured whenever you begin fastening on the automobile’s entrance facia. One among my system’s in Scorpio loosened off after I was driving on tough roads. The plastic cupboard to the Printed Circuit Board (PCB) are of inferior high quality and the contact display screen will be scratched very simply.

Some 9” programs screens had Gorilla glass and have been good, contact was discovered to be good too. The present ones which I fitted on Swift ZXi & Scorpio are having nicely construct and are nonetheless serving the aim, no complaints but. The one which gave me complaints aren’t any extra within the automobile. I’ve made few evaluate movies based mostly on my expertise; video hyperlinks are posted in your visuals.

Energy perspective:

From the facility perspective, I discovered that the standby present that flows via the Android AHU when ignition secret’s eliminated and the automobile is parked is 10 mA which I discovered to be negligible for a totally charged battery. The one I examined is the AHU that goes into Standby state and never utterly OFF state, this technique involves ON state immediately when Ignition Secret’s switched ON to Equipment Mode. The AHU that goes into full shutdown are principally high-end Android AHUs that sink 1mA of present, however they re-boot each time when ignition secret’s switched ON. In case you have checked the 1-DIN Audio programs, they used to sink 1 – 5 mA in olden days, there are 1-DIN nonetheless in use.

As I discussed earlier, the Android Software program & {Hardware} has room for enchancment, there are particular bugs, one such was discovered by me is a battery draining bug. In my android system put in in Mahindra Scorpio S4, I had my Radio utility working and as I eliminated Ignition Key after I parked and locked the automobile. The battery was discovered to be drained put up 2 days and the engine was unable to crank, I had to make use of my bounce starter. After some trials I discovered that the Radio chip was ON and it was not permitting the interior circuitry of the Android System to enter Standby mode. How I discovered the Radio chip was not turned OFF by the Android System is, first I turned-OFF the Radio from the Person Interface and nonetheless I heard a feeble Radio channel’s sound from the Sub-Woofer though there was no sound from each element audio system. Secondly, the standby present consumption rose up roughly to be at 400 mA after ignition key was eliminated and the system’s display screen was utterly OFF. I re-confirmed the identical after I turned ON the Again Lights of the Keys, specifically – Energy, House, Again & Quantity Keys the place they remained lit even after I eliminated the Ignition Key. This proved that the Radio chip was not permitting the Android motherboard {hardware} to enter standby state.

One other experiment I did was I changed the above-mentioned head unit with an upgraded {hardware} and software program. After a radical examine, I parked the Mahindra Scorpio for a month. In every week I used to examine and begin the engine for couple of minutes for oil circulation of the diesel engine. I behaved nicely. Roughly after a month, the Scorpio didn’t begin and I needed to bounce begin it. The battery is new and with the identical battery, Scorpio begins effortlessly even after 3 months of lengthy storage with a branded JVC or Alpine Audio Head Unit put in. I eliminated the android system for the debug and came upon that the system in standby mode consumes a present of 10mA from the battery, which suggests an influence of 120 to140mW is consumed when the automobile was parked. Under is the video that explains the problem intimately and a workaround to resolve this battery draining concern.

Android Audio Systems found unsafe for vehicles, here is the workaround video


If you need to make use of an Android system in your automobile, it is advisable choose the AHU from reputed producers like Blaupunkt (Key Largo sequence), Pioneer, Nippon and Maisun. Nonetheless, these programs are steady and prices a lot. If nonetheless you need to use a decrease value finances system, be ready for dangers and it’s instructed to maintain a totally charged Soar starter in your automobile in case of any untrodden battery drain occasions occur. The Maisun Android Audio system is discovered to be an outstanding amongst all because the Audio copy high quality is at Hello-Constancy and excels in all even in energy saving when automobile is turned OFF utterly. I personally personal a Maisun in my Suzuki Swift ZXi, you’ll be able to watch the video within the final hyperlink under.

The one factor I didn’t like about Android Automobile Audio programs is the apps updates that it wants often, which is time consuming and hook up with WiFi each time for sooner updates and installs. If you have already got an OEM contact display screen with Navigation that’s the finest and at all times will likely be my first desire contemplating the security, high quality and right here the OEM is accountable to deliver that to you. The programs that I attempted under within the movies are the place there was no contact display screen nor a navigation unit, therefore it’s my ardour to deliver what I did on my automobiles
