There is not a service providing business, delivery man or local that does not have one of these babies tucked under their seat.  This is a must have for any visitor or resident of Southern California.

The T-Guide is an extremely easy to use reference guide for every address, street, freeway and destination in the area.  Don't know where you are?  Pull over and get that gas station's address - or find your cross street (all major street signs will tell you what city you are in and what block number you are on).  Look up the street and then block number.  Next to that block number is a page number and map coordinate.  Go to the page number, and find your intersecting coordinate on the map....that's you sitting right there.  Look at the extreme edges of your page (see those number in the white arrow?) that the next page where your map continues to show your travel progress!  

You will never stay  lost with your T-Guide.
