Have you opened the attachment in the above post? That should explain if I'm joking or not.
I had about 4-5 other ones just like it saved, but when TMC updated their site, I think I lost all my previous attachments. They're somewhere posted in other threads.
And in case, after clicking the attachment, it's not obvious - yes, I'm joking. The nav is horrendous. It does stupid things, ALL THE TIME. When I take long trips, I use Google Maps on my cell phone right next to the huge 17" screen, because 10/10 times my cell phone will route me better.
