searching street names


today i found a cool way to search for a street names on my nuvi 360. Im sure you guys might already know this.

"where to?"
"pick which state"
"search All"
"skip "the enter house number" by clicking done
"enter street name"
"choose the top choice for "Aly, Cir, Ct, Ln, St" etc
"then choose city"
it seems to work sometimes but not always which i don't understand why...
