I'm also looking at getting one (CK3100) installed. I got a quote from Carkits.ie for €318 inc vat and that is also including the extra cost for the Bose system cable harness.
I have been pricing parrot car kits up and although carkits.ie are probably the best they aren't the cheapest. I got a price from parrot.ie on the CK3100 and Ck3200 and its cheaper than carkits. Funny thing is they actually use carkits to install them, must be taking less profit on the actual parrot maybe. Other places are Car Phone Warehouse and komplett but komplett don't do installation.
Just purchased ck3100 from [broken link removed], installation is by carkits.ie and cost 219.99, happy days i thought. Will post the outcome of installation etc.
