As someone who has also worked with Microsoft Dynamics - mostly the other products, which are IMHO at least an order of magnitude more complex from NAV/BC - you can customize it heavily, but the high complexity will get to you. Some things are actually rather difficult to do (e.g. anything to do with Ledger or BOM calculations).
Adapting Dynamics ERP to business process is a challenge of its own, and not every company can do it. At least it's possible in Dynamics, SAP is a mess - most customers I know with SAP have to use external software and import/export for significant customization.
