Although Pioneer's car navigation system has good performance, support is very bad, and software navigation studio for updating map data can only be used on Windows.
If you do not have Windows PC or Internet environment, we recommend not to buy.
Windows is very damaged by viruses and spyware, it is not well-named because it has many annoying functions such as UAC.
Moreover, since Windows PCs are diverse, there is a possibility that depending on the environment, it will cause errors and spend wasted time.
I am very sorry because I only have a Mac.
