The latest update deleted my navigation button completely, and the new Google Maps is horrible, it now take several clicks to get to the navigation, and crashes constantly.... I use the navigation almost every day and I hate hate hate the new maps update

Last night I went in and reverted to the original version but this morning it had automatically updated itself again.

Is there any way to permanently keep it from updating?

I am on a Nexus 7 3G.

I used to be the biggest Google fan but I am getting fed up...... I don't use Facebook and am REALLY sick and tired of Google trying to FORCE me Into using Google+

I am thinking of trashing everything Gmail, Picasa and Google but where oh where to go?
