At present, China's on-board GPS navigation equipment can be divided into two categories: one is brought by the original factory; The other is later modification and loading. Customers can distinguish between the two from navigation map, price, map promotion, after-sales service, etc.

How to identify the original car navigator and rear loader?

Navigation map: since the car front is matched with a special model, the car front is generally the same for the same model. If I prefer to use Gaode's map, but daotong map is installed in the model I choose, then users can't choose according to their own wishes; Flexible software configuration is the biggest advantage of rear loader.

Speech problem: a common problem with on-board front loading on most imported vehicles is that there is no Chinese map on the front loading machine, and there is no way to install the corresponding navigation map. There are more problems such as no Chinese interface, which makes the valuable on-board front loading become furnishings. Rear mounted navigation generally does not have this problem.

Price: the maximum price for the front mounted on-board navigator can be 20000 days, but the price for the rear mounted navigation is generally more than 4000.

Map promotion: the original GPS is mostly CD-ROM, and the promotion is very simple. As long as there is promotion navigation map CD-ROM to directly replace the original, but the promotion cost is the highest. The promotion price of genuine CD-ROM electronic map is more than 1000 yuan in 4S store, and the promotion price of pirated CD-ROM is about 500 yuan; Post installed GPS promotion is generally SD card promotion, which is to copy the new electronic map to the SD card. The promotion cost is slightly cheaper than the pre installed one, and the estimated price is about 160 yuan.

After sales service: if the front loader accidentally breaks down, it is more troublesome. It also needs to drive to the 4S store and contact the manufacturer's technicians for repair. The warranty time of the whole machine is one year. If the warranty period is exceeded, the user can only spend nearly 10000 yuan to replace a new product or leave it idle.

How to choose the rear mounted navigation?

How to choose when there are many functions: now GPS navigation products have different selling points, but in the final analysis, they are nothing more than video screen, audio, entertainment, 4G, navigation and other functions. When purchasing an all-in-one machine with more functions, in fact, the most important thing is to look at its navigation function. Navigation accuracy and humanized design are the most important factors,

In addition, for some owners who are unwilling to load the vehicle host, when selecting the portable car navigator, they need to pay attention to: when the product presents the same shape and different prices, customers need to distinguish the authenticity from the Chinese Suffix: many product suffixes use the Chinese suffix, that is, if they have the same shape, customers only need to see the product model Whether the suffix is consistent with the Chinese and English names. In addition, the outer packaging box of genuine Chinese machine is basically printed in Chinese (except for some product models), the reverse side is pasted with "anti-counterfeiting label", and the operation keys are printed with Chinese font.
