I spotted on the web that Nokia have now released the 5800 Navigator version in Europe. Basically the same phone as the 5800 Express Music that is available in SA, but comes with a free lifetime voice guided navigation licence. It might be worth enquiring from Nokia SA if it will be coming here if anyone is considering this phone soon.
Something I have found irritating about the 5800 (and I assume other Nokia Navigators) is that the map does not orient itself to the road you are driving on. Sometimes the map travels across the screen, sometimes even backwards. What I'm looking for (but haven't found) is a setting like the the Garmin "Track-up" or "Automotive Mode". Does anyone have any input on this?
Having solved the unzip problem, I've also got smartGPX to work well with a PQ extracted from an e-mail. Something I've yet to try is to store the extracted gpx files in the phone's internal memory, replace the 5800's microSD card with the one from my Oregon, copy the gpx files from the 5800 to the Oregon's microSD and then put the card back into the Oregon.
I believe that the Oregon will find any gpx file anywhere in internal or card memory, so the latest cache data should then be available for paperless caching. This would enable PQ's to be created, received, extracted and transferred to the Oregon without a PC. A complete mobile solution! All that's worrying me is the possibility of corrupting the Oregon's card in the process. Any SD expert's comment on the safety of this idea would be appreciated.
