Mud Map 2 and Mud Map HD are two different apps with different map engines. Each map engine has different features and advantages.
Mud Map HD uses SmartTOPO, based on NAVTEQ commercial grade data and has auto routing.
Mud Map 2 uses THEMAP, a map engine we have developed as part of a community mapping project. It allows community members to contribute data to THEMAP and allows for monthly map updates.
If Mud Map 2 was released as part of an update to Mud Map HD users, it would automatically replace SmartTOPO with THEMAP and force Mud Map HD users to loose their SmartTOPO license. This would not be good for Mud Map HD users that like using SmartTOPO. When purchasing Mud Map HD in the description it states that purchasing the app gives users access to SmartTOPO, so we do not feel it would be fair to take this access away from users and force them to use a totally different map engine.
We are no longer offering SmartTOPO to new customers, however we want to continue offering Mud Map HD customers the product they paid for. We have a number of free updates planned for Mud Map HD in the future. These updates include access to new maps, as well as the usual maintenance updates.
Mud Map HD users choosing to also purchase Mud Map 2 can do so if they wish. This will allow them use to both apps and map engines. It will also allow for importing of existing maps and data between both apps.
