I\'m inserting a very basic Google map into my page and the zoom control and streetmap icon are not visible, however if I place my mouse over where they should be I can zoom
Note that on the moment it's not even possible to show the full size zoom slider on touch devices (ipad etc). Here's the documentation:
http://code.google.com/apis/maps/documentation/javascript/controls.html
google.maps.ZoomControlStyle.SMALL displays a mini-zoom control, consisting of only + and - buttons. This style is appropriate for small maps. On touch devices, this control displays as + and - buttons that are responsive to touch events.
google.maps.ZoomControlStyle.LARGE displays the standard zoom slider control. On touch devices, this control displays as + and - buttons that are responsive to touch events.
