Review on Garmin Navigator Detailed China MicroSD by Justin Miller

I bought this with a Garmin GPS (and found I paid significantly more than if I had gone to WalMart). Brought a GPS navigator and SD card to China and found the combination almost useless. In Shanghai, it was not possible to detect it with an accuracy of 0.5-1.0 km. Outside of Shanghai, when driving, it usually showed the GPS position about 100 meters from the road. Would happily pay more for an accurate map to use in the US from Garmin as none of the local GPS units offer English street names or English verbal cues (the reason I bought the GPS and map). SD card). Came back to the US with the GPS module and found it to work perfectly, so confirming that when used in China the maps were either inaccurate or not Garmin compatible. I would not recommend this product and was very disappointed with the response to my inquiries. Garmin products are usually very good, but this one failed. I think my next GPS purchase will be from one of Garmin's competitors.
