The amount of RAM memory.
Many modern premium car radios, as well as regular models, are close in functionality to tablets or even laptops; this is especially true for models that carry a full-fledged Android operating system on board. Accordingly, information about such devices may also contain purely "computer" characteristics, such as the amount of random access memory (RAM). The more “RAM” (
4 GB or even
6 GB) provided in the system (ceteris paribus), the better it works under intensive loads, the easier it is to cope with “heavy” tasks (for example, resource-intensive applications) and performing several tasks simultaneously.
At the same time, note that manufacturers of radio tape recorders, usually, equip their devices with a volume of RAM that is quite sufficient for solving basic tasks and working with built-in programs (
2 GB or less). Therefore, quite often information about the amount of RAM is more marketing than practically significant — it is designed primarily to create an appropriate impression of the product. It makes sense to pay attention to this characteristic if you plan to run various additional programs on the device.
It is also worth noting that different software platforms have different requirements for RAM, and the characteristics of the processor (see below) also affect the overall performance. Therefore, only models w
...ith similar processors and software can be compared with each other in terms of RAM.The colour of the backlight plays primarily an aesthetic role, allowing you to choose a radio for the design of the dashboard and user preferences. In addition, some colours have a practical meaning. So, the
red backlight is extremely popular nowadays also because it is almost perfect for the dark time of the day: this shade does not knock down "night vision" and has a stimulating effect on the nervous system. And
green, on the contrary, relieves excessive nervousness and promotes peace of mind. Other popular colours in modern times include
white,
blue,
orange,
yellow,
purple ; they do not have such pronounced effects, here the main selection criterion is “like or dislike”.
Also note that in many models several backlight colours are indicated at once. This means that the device has a backlight with adjustable colour selection. At the same time, there are models with a choice of a full range of RGB colours.
