need directions how to get poi's(kml) to work in app

ive loaded poi (klm) folder from google earth into my laptop, then from there to my
"poi" folder (inside "other" folder)ive created on my microcard in my phone.
these folders contain hundreds/thousands of grouped poi files (subway, mcdonalds etc.
)...then tried to import as kml through app, and nothing. thanks for any info anyone
can provide.
