I just put the latest mapthis which I think its 520 something like that. But it's not the beta 505. I downloaded nieko's mapthis and the maps work fine it's just that the gps receiver 290 doesn't receive any signal. I was wondering how to fix this so that I have some bars. For the configuration i.e. ENABLESERIALPORT I put 0 and I left everything else as is. What should I do?
