Info Needed On GPS System

[LAT4R]

I have searched and read the threads but i cant seem to find this info but i know i have read it on here before. I am looking to get an after market GPS system. I read on here that one of the models will zoom in to some level at every intersection. Can someone tell me which model it was that was doing this and is there a fix.

Thanks
Wayne

And Merry Christmas to All!
