My first post - pls. go easy on me.

I have nuvi 1300. I need the Nuvi to show me the speed limit of the road I am traveling on. I downloaded acleite's file from [Only registered and activated users can see links. ] and extracted it into the root of an empty sd card. However, I did not get the Nuvi to show the speed limit of the road. What am I doing wrong?

Details of my Nuvi -
SW Ver 5.90 S4_R3 V4 2GB
Boot BLK B1104-00 6.10
X-Loader B1104-00 6.10
System B1104-00 5.90
USA Lifetime Maps

Thanks in advance.
