What is RAM used for in an android headunit?
How much RAM does and android headunit need?
Can I upgrade to more RAM in my android headunit?
R.A.M. is an acronym for Random Access Memory. The meaning doesn’t help explain its use in an android headunit but the letters RA and M appear in every listing or sales literature ever written for an android headunit.
What does RAM do?
RAM is the temporary store in the android headunit that the program information lives in while its going to of coming from the processor. The processor uses the information stored in the RAM to make the apps work.
How much RAM to get
Because RAM is so closely linked to the app and the apps are mostly targeted for the mid to latest generation of phones, the android headunit needs to match that, at least. In order to run the apps well (quickly, fluidly and without staling) the RAM in your android headunit should match that of modern phones.
Buying an android headunit today with the RAM levels of 2013 won’t give you a nice and enjoyable experience while using the apps of today. Todays apps are not built to run on such limited RAM.
Getting more RAM
In this post we discuss adding more RAM to an android headunit. The TLDR; is that unlike laptops, you can not add more RAM to an android headunit.
Right first time
With no option to upgrade the RAM in the android headunit after purchase, it is an important decision to ensure the right model is purchased.
Future proofing your android headunit is an important consideration. You phone may well have been upgraded several generations over the life of your android headunit that still has to run the latest apps. Picking an android headunit that will still operate fluidly and smoothly with apps of the future requires ‘Future Proofing‘. This is a purchase decision, not something that can be done later. It goes hand in hand with the processor as RAM only plays a part in Future proofing, but it is a major part. Pick the android headunit with the most RAM you can afford, not forsaking the processor. This will be your best effort to future proof your android headunit.
How much is too much?
The is no ‘too much RAM’. Any RAM that is unused at the time makes no effect on the rest of the headunit. But it does give an option for that RAM to be use at a later date, say, after the play store has updated the apps.
The numbers next to the RAM are often listed in Gb (gigabytes). Gb can be compared with Gb, Mb (megabytes are a 1000 times smaller than a gigabyte) can be compared with Mb. 1Gb is also 1000Mb and this is the absolute minimum specification RAM for an android headunit designed in 2013. Now virtually obsolete the 1Gb RAM models struggle to run modern apps well and this will only get worse as apps get bigger. 2Gb RAM, while being double of the 1Gb, it is a long way off the 8Gb RAM found in the latest models of android headunit. 4Gb and 6Gb are good mid range choices, while 6Gb RAM is less common, it gives more Future proofing than the 4Gb RAM.
It’s not all about the RAM
While it’s not all about the RAM, it does play a very major role in the android headunit, next to the processor. Pick a fast processor and plenty of RAM for a good starting point to finding the right android headunit for you.
