Hello

Has anybody used this GPS navigation system for mobile phones nav4all? It should be something like TomTm... which reminds me to ask about impressions from it as well .. The thing is that nav4all is still in a trial period and i can download it for free, but... i don't have a gps receiver... and i'm not too eager to put money in it if after i'll be disappointed by all these mobile phone softwares.. Which leads to the key question - should i go for a conventional nav system (by conventional i understand the ones that stay in the car), or should i get a GPS receiver with bluetooth and count on those phone solutions...
