Thanks, I looked into my upgrade options and personally don't think spending the money to get an entire MK4 system (excluding the screen) is worth it. For $100 I would do it but most of the used ones I see for sale people are asking $500-600 for what amounts to a 10 year old navigation system. For $875 I can get a Dynavin Android which is far superior to an MK4 system and will still maintain the OEM look.
