Hi Saad,

I just ordered some semilegal datacables for my Magellan Explorist 200 and now I can download and upload waypints to my GPS, just like the more expensive models. It's neat but not more than that.
Until know I used the GPS in combination with a normal map and it works fine sofar. I made a custum grid on the map and I did some treasure hunting (geocaching) to practise and it pinpoints my location with 5-15m accuracy, also in the forest.

I've cycled through Jordan and Egypt (Sinai) in February this year,
here's the link: http://images.exploder.org/gallery/jordanie-egypte
The Wadi Rum and Sinai part are at the end of the album, from page 7 onwards. Click on a pic for the english text.

I really enjoyed the trip although the weather at the start was very cold (rain, mist and snow in the desert). In the northern part (North of Petra/Wadi Musa) Palestine and Jordan kids like to throw pebbles at cyclists. Quite annoying.
As you live in Jordan do you perhaps know why they do that?

Overall the people (especially the Bedouin) were very welcoming and friendly and helped me to cross part of Wadi Rum on bike. I am now sure you can cross the whole of Wadi Rum starting in Rum and cycling SE to Aqaba. The road is very sandy in the beginning and you can't cycle (I took a jeep) but after 15-20 km or so the road gets better. You'll need three days of water and food or ask the Bedouin in Rum for the locations of their wells or tent villages.
I used old US en Soviet army maps together with satellitepics from google earth but perhaps you have access to better Jordan maps...

Cycle the world,
