please help me. Im new in this forum and Im from Mexico, so please be kind with me and my english too

I have a Garmin nuvi 1300N and allmost everithing woks "great". the problem is here:

Many streets in the device are in the wrong direction (opposite way) but I dont know since when, because I noticed this when I was testing my device in my own town, and the surprise was when the GPS tried to take me in the wrong way to my destiny, so I checked this with the basecamp map installed on my Mac and there appears the streets in the correct direction, so I deleted, installed, reinstalled different mexico´s maps, I did a reset by Holding the right bottom corner of the screen etc... on my device but the streests still appearing in the wrong direction.

How can I fix this?

do I need to format and reinstall everithing on my device?

Thankyou for your help
