I just went and updated a TZT2BB from 8.01 to 9.01 today and what I found is on v.8.01 I had to turn off the triple play mentioned previously by JE for it to not "zoom in" after hitting it's waypoints.
Now when I updated to v.9.01, of course I have to run my factory clears on it (for the main unit and the fish finder). This reset my clock amongst other settings to their default values (e.g. GMT+0) but no biggie I know what they are and just go and toggle the settings I want on, setup the fish finder transducer selection, check radar source, et. al.
It appeared that the v.9.01 did reset the three settings to "on" by default. So, if I had updated my box and just left it, sure enough the "symptom does occur." However - I went and turned off these settings in the HOME > SETTINGS > ROUTES and other places mentioned before running my test.
Sure enough, if you have turned "off" the culprits prior to making gotos and routes, this symptom of "zooming in" does not happen.
For customers experiencing this, please check for the proper settings related to waypoint zoom previously mentioned every time a "factory clear" is performed.
Hope this helps, :sail
