can i just direct swap?

[ian]

With regards to the GPS antenna on the RNS510, I read that it is not necessary for newer cars with the shark fin antenna mounted. Is that true? Can anyone confirm that? I'm assuming that'll make hardware installation a direct swap (without needing to find a place to mount the GPS antenna - i.e. on top of the aircond vent)?

If your car wasn't ordered with a Rns 510 it will come with just an ordinary Aerial ,the GPS antenna works very well on top of the unit sitting on the metal bar that runs through the dash

That's what I thought. Was slight confused with this:
DIY - RNS510 Install

3) Satnav Antenna

The RNS510 comes with a satnav antenna which plugs into the back of the unit. It plugs into the blue socket. If you have a shark fin antenna installed on your car, this antenna won't be necessary as the shark fin can be used as the satnav antenna. The satnav antenna feeds up through the vents and can sit near top middle vent. The antenna however is also magnetic and can be attached to a small piece of metal for easier fitment.

I have the MFD2 fitted with the Shark fin antenna. Does that mean if I change over to an RNS510 that I can just plug the existing antenna into the new unit, or will I need some sort of adapter?

thinking of getting a MFD2 to replace the stock radio... can anyone advise what else will need to be purchased to get the sat-nav going.. gps antenna , canbus etc ?

done a search and bit of a noob when it comes to sat navs so im now more confused
