Thank you so much for your message! I have found instructions on updating Vehicle Manager Component here:
http://ordasoft.com/News/Vehicle-Manage...ehicle-manager.html
UPDATE INSTRUCTIONS FROM PREVIOUS VERSIONS TO PRO WITHOUT LOST DATA
Full save so files and folders:
{yours site}/administrator/components/com_vehiclemanager
{yours site}/components/com_vehiclemanager
Please do full Database backup.
Please do full vehicles export.
After that please remove
{yours site}/administrator/components/com_vehiclemanager
{yours site}/components/com_vehiclemanager
Please do install Vehicle Manager new version.
Please recover folders:
{yours site}/components/com_vehiclemanager/edocs
{yours site}/components/com_vehiclemanager/photos
{yours site}/components/com_vehiclemanager/media
Also you will need upgrade all plugins and modules
So do I need to uninstall the Vehicle Manager Component using the Joomla Extension Manager, or do I simply delete those folders?
