I have a problem with copying to the SD card in the nuvi 3760T with original firmware 3.60 and Transcend microSDHC card 16GB class 6
Copying of wiles is dead slow, only 35 KB/s !
Anyone else has faced same problem? Solution?

What results do you get from your cards?

In theory it should be at least 1.8 MB/s, like the internal memory of device.
