Finally i am using the bluetooth function of my mobile phone. I downloaded a navigation software nav4all onto my mobile phone, just with a gps receiver, it's a perct saving,convenient and accurate navigation system already. i like it very much.

My mobile is a nokia n70 the smart phone,
depending on the network you use, you can have unlimited internet surfing for under £7 i connect onto my pc using bluetooth and i just pay my set fee. amasing value. i like my mobile but have got my eye on the Nokia 91, sexy phone.xx
