1.6.1 update a money grab?

I updated to 1.6.1 after map loading issues with my older version. This version re-enables my third-party maps to be identified and loaded in the app. BUT, it appears to be only a 5-day activation! And the "Buy one Import 3rd Party maps" is listed at $28.99 CAN! The programmers should not implement poorly-documented changes in the way the app handles - and charges for - digital maps. For this added cost, the total price for the Memory Map package exceeds that of more capable navigation apps.
