Is it possible to install a Satnav unit from an n-tec model (original equipment) straight into a 2005 Nissan Micra 1.5DCi Sport Plus model? Are the connectors the same? Is it a straight swap and plug in or are other components required such as modulator...GPS antenna quoting examples? I have the entire unit from a 2009 Micra n-tec model including fascia surround.....I know how to remove and install...thats not the problem....I just need to understand whether compatible? With thanks....anyone
