Anybody know how to master reset subscritions on a GTM-25? Seems there is a maximum number of entry attempts (16?).

Installed "Australia All" then, then trying "Europe all" got error "Cannot add subscription. You have already added the maximum number of subscriptions". The GTM table at that point had 16 entries, 8 x Australia states listed individually and the first 8 EU countries.

To remove a subscription you still need to add one (eg Vendor ID = 0) so catch 22 and still getting errors and unable to remove single subscriptions. Interesting however removing "Europe All" still gave the error but unit then rebooted itself and the 8 EU countries were gone.

Adding "US & Canada All" then worked OK and can now see Aust x 8 and these two entries (US & Canada) for a maximum of 10 in the table....but still getting error trying to add anything else including a single subscription.

Any ideas?
