1. The product representing the latest technology is the GPS product using the third generation chip of Cerfu. GPS core chip is very important! These are all related to the GPS product's star seeking time, positioning accuracy, drift performance. Many GPS manufacturers can produce GPS products, but different manufacturers may use different GPS core chips, so the products produced will be somewhat different due to different brands, core chips, materials and processes.

　　2. Product appearance design, product accessories, battery selection, etc. are also a side reaction of the quality of the product, and will also be consumption oriented. It is recommended that you first choose mainstream Bluetooth GPS, and then choose fashionable GPS. Recently, there are very cheap Bluetooth GPS on the market. The author still suggests that you take a careful look. At present, those cheap GPS products are mainly produced in Shenzhen, or some products choose non mainstream GPS chips. If you really care about the price difference of one or two hundred yuan, you can consider buying the cheapest products.

　　3. When purchasing Bluetooth GPS, the price and after-sales service of these products also reflect the marketing attitude of different manufacturers and agents. We recommend that you buy products that are guaranteed or sold by companies of a certain scale. At present, Bluetooth GPS has the so-called difference between smuggled goods and licensed goods. At present, there are no counterfeit products! So: Bluetooth GPS products alone, whether they are distributed by domestic general agents or goods from Hong Kong and Taiwan, are actually products of one company, and sales companies can basically buy them as long as they are guaranteed. The price difference between the products distributed by the domestic general agent and the goods from Hong Kong and Taiwan is about 20 yuan. Compared with the companies with a large number of distribution, the price difference of 20 yuan is not less. However, for customers, if there is any after-sales service after purchasing the goods from the domestic general agent, the security factor is also higher.

　　4. The performance of Bluetooth type GPS of mainstream chip products is now very stable and mature. In China, since 2006, more than 5000 Bluetooth GPS products have been sold every month. Almost 90% of the mainstream Bluetooth GPS products are produced in Taiwan. These products are also popular in Europe and the United States. Search some foreign GPS sales and information introduction websites, and you will be familiar with the pictures of these products that are popular in China. Very familiar products include HOLUX's GPS236, Guantian's GPS238, HAICOM's 406BT and 406BT-C, Huantian's BT-338, Changtian's GPS - 6033, Litai's 953X, Dingtian's mini 2000, V700, Gaorui's solar energy series and mini series. The price difference of Bluetooth GPS products of different brands is not too big.
