i have installed igo primo on memory card but every-time i try to run it i get an out of memory message or a box saying program memory is very low message,ive already had igo 8.3 running on my navman no probs,does anyone know how to fix this and what the problem could be,thanks.

One:
Primo is very hungry on resources. AFAIK the s30 has only 32MB and is 320*240.
Now I am saying this because 32MB is far less than the 64MB that is recommended for Primo. And more, because the 320*240 resolution is not supported originally, you are probably using a changed 320*240 (Amigo) resolution. I noticed the 320*240 data.zips around seem to need more memory.
I guess Primo won't run on many devices flawless or nothing at all unless a proper data.zip is released.

Two:
I also noticed the unlock method used is giving trouble sometimes. This could also be a reason.

thanks nabi will just stick with igo8 for now,but i liked the look of the junction view,cheers.

The junction view is nice, but it's no more than eye candy. And it's not everywhere.
The iGO signposts are nice too. Just my 2cts

There is always the option of ditching the .dem files from Primo and not using a TTS voice. Ditching those two things will free up a lot of memory. It's the same trick Mio c220 owners use to run igo8 on their devices, it still applies with Primo and some 64MB devices.
