Bolero Unit on Superb MK II 2010

Hi all. New to this forum and wanted to start a topic about Superb MKII Bolero Unit. Available options for Bluetooth and SatNav upgrade. There are few posts on this but the links are not working. 

Basic understanding was that there are two types of Bluetooth kits

1. Which adds the basic bluetooth telephony to the head unit/speakers

2. Which adds RSIM features and displays all the data on the screen

But is there a better option in 2017 with better devices being launched. 

Also share any options for SatNav upgrade 

Pls share ur views.
