If you are interested in buying a Garmin nüvi GPS device then I recommend that you don’t buy it from the Garmin dealer in Saudi Arabia, Darmoja (دار موجة). Their prices are outrageous!
I will give a few examples, Garmin nüvi 5000 cost over 3200SR ($854) from Darmoja. It cost only $485 (1819SR)! Almost all other Garmin nüvi devices sold here cost almost double their prices on Amazon!
I bought a Garmin nüvi 760 for 1425SR ($380) and it cost over 2500SR if I bought it here. They do come with Arabic language support and I would not worry about the Saudi Arabia Garmin maps, their 2008 Middle East map is the same as the older ones, but that’s a topic for another day.
You should do the same, buy it from Amazon and use myus or Aramex to ship it to Saudi Arabia. Do not support those outrageous prices!
