I sent the axure prototype in rp7 to my customer and he had dissatisfaction because he’s trouble to read the text size too small with sitemap area , not cleary visibility sitemap and prototype on his mobile phone.

Maybe you could create your own sitemap and ditch Axure’s… sort of like a normal mobile navigation menu then wire those links to open the corresponding pages? It’s not ideal but it’s a workaround.
