my service contract is about to expire...what is a good land rover maintenance workshop other than Al Tayer?

i got the 2010 UAE Nav map dvd from a friend for LR2...i inserted it in the dvd player and an error message "error reading the nav. maps data".....should i ignore and keep in the dvd and it will work eventually after some time maybe a couple of hours as some of the posts are saying? or do you think the dvd i received is faulty second question: where is a good maintenance workshop for Land Rover other than AlTayer as my service contract is about to expire and i will have to resort to an external workshop?
