Sorry if I annoy you but I checked the tutorial and I couldn't find this tutorial.
I found a link to "Tomtom Go 910 Dismantling Manual.pdf" but the link is not showing me the manual.
Please check this link and you'll be lead to a search site of crocko, no manual !
[Please Register or Login to download file] And besides that, not all people are as familiar with the site and the search engine as you are !
It took me some time to find the right search tags to find the (not working link) to the manual.
I think this is a great site for help on all navigation problems but you forget that also people with not that much knowledge of computers and navigation visit your site.
