otimização de memoria igo primo 1.2

[victor.ciaco]

Ola galera, sou novo no blog gostaria da ajuda de vcs. Comprei um GPS Roadstar RS-610GPB (64mb) memoria.
Instalei um IGO Primo 1.2 mas to tendo problemas com memoria (Crash)
Alguem poderia me orientar como modificar o sys.txt para corrigir o problema?

O sys vem assim:
