Are you going to install it in the car? There are Lu Chang, Ge Fei, Casta, Ke Junda and so on in the car. I suggest you choose from these brands. Lu Chang's navigation update is the fastest, and its versatility is good. Other models are also of good quality.
Please pay special attention to the following points:
1. If it is a CE system, it must be an ARM solution machine. Don't buy machines with MIPS scheme. Upgrading MIPS scheme will be more difficult.
2. Navigation must use an external SD or TF map card, that is, you can remove the map card at any time and upgrade it on your computer. Never buy a CD-ROM version of the navigation, never buy a navigation with a built-in hard disk, or you will be kidnapped. After the upgrade, it costs hundreds of dollars, usually more than 1000. I guess you didn't steal your money.
3. The running memory of 3.CE system should be at least 128M (not storage space), preferably 256M or 5 12M. The resolution should be HD 800*480. If it is an Android machine, the running memory must be at least1g.
4. Be sure to ask whether the machine port is encrypted before placing an order. If the port is encrypted, you will cry in the future. Other maps can't be installed, so you must pay to upgrade the original ones. Therefore, the port needs to be unencrypted, and other maps can be installed.
5. Send a 4G map card? It's too small, at least 8G, 8G can hold a full version of the map, preferably 16G, and can hold more than 2 sets of maps. I can't find a place on a map, so I have to find another map. I installed five sets of maps at a time.
I'll talk about other matters when I remember. I am also a navigator. This is my experience. So many words are typed by hand, which side is not copied. You should give more points for typing so many words. Listen to me, you can't go wrong. All the money saved will go into your pocket.
