I am in my room at Hem 18B, Nguyen Thi Minh Khai street, DAKAO ward, District 1, HCMC, Vietnam.
My house address is 18E1 NTMK street, DAKAO, Dist. 1, HCMC, VN.
I am using a Nokia E72 smartphone with Google.maps to navigate the streets and provinces of Vietnam. It works very well. I recently navigated from Phan Thiet to Saigon on my motorbike.
It took 4 hours, as there was lots of road work to upgrade the highway making it wider and safer.
I am still learning how to enter the coordinates for the mapping. I just read from my phone using google.maps.
