[Electronics-talk] GPS Similar to Origional Trekker?

[Sarah Clark]

Hi Everyone,
I had an origional Trekker with the Dell PDA, and sadly it no longer works properly. I loved using it to learn new places because it would allow you to browse streets one block at a time, by pressing the navigational keys left right up or down. This gave me a really good picture in my mind of all of the intersections along a given street, and where streets were in relation to each other. I know there is a Trekker Breeze now, but that does not allow you to browse virtually like I am describing. I have an iPhone now, but none of the GPS apps I know of allow me to browse streets by block like the Trekker did. With the flat screen it seems you have to drag your finger along the street to navigate it, and it is very difficult to keep my finger on the street using the flat screen. I am looking for a GPS option that will allow me to explore streets from one intersection to the next, by pressing some sort of button, or perhaps making some sort of swipe gesture, to advance along the street. Does anyone know of such a GPS program? It can be an iPhone app or some stand alone GPS system.

Thanks for any help you can provide,
Sarah
