navigami

Hi all,
My mobile is a nokia 6230
I'd like to know if navigami works on it. I download navigami.jar and navigami.jad in my pc and i connect the mobile through infrared.
When i click install (in pc suite) it says "impossible install the application, dimension file are too big"?
I discover the maximum that nokia 6230 can download is 128 kb while navigami is 218kb.
How can i do?
How can i install navigami on my nokia 6230?
Please tell me each passage to do.

Greetings from Italy
