Yes. You will have

in your contacts list.
You would just have to press the box at the end of their name to give you the info about which number it is.
Only slight downside is that if you use the Fiscon display in the MFD to make calls, then you'll presented with two Daves as contacts and won't know which is the mobile number and which is the work number, for example. For me, the major drawback is that Fiscon doesn't display the recent calls list from my iPhone (calls made during the day when not connected to Fiscon).
Its not really a hardship if you use the MFD to navigate to the phone book using the Fiscon as you will be presented with two Daves but it doesn't dial blind without showing you the number first. When you select OK on the steering wheel it then presents you with
12345....

with dial already highlighted, you just need to click ok on the steering wheel again.
If its the wrong Dave just go down one and select back and it will present you with the other Dave
56789....

I'm really pleased with the way it integrates with the Sony Ericsson I have. Missed calls, dialled, received all populate on to the fiscon as soon as it connects via bluetooth. It obviously downloads all the details from the phone. When I first installed the Fiscon It even told me on the MFD if I had a new SMS and allowed me to read it and browse through the others. I could also send from previously composed SMS. However I tried looking through my SMS the other day on the MFD and it was old ones from way before Christmas so I don't know if they have to be deleted to make room for new ones!!
It can also have up to 5 mobiles paired with it. So if my Mrs takes the car out she doesn't need to mess about pairing her phone, it happens automatically with all her numbers showing on the 510's display.
