Peugeot 607 with Wi-Fi

Hello forum, I would like to install WLAN in my 607 and ask you if someone has ever had problems with a notebook or similar devices in 607. Car type see below. What do I have in mind. . . . I have an RT3 Navi, in which you can unlock the audio connection in the glove compartment (with the latest software version 6.61). Since I don’t have half things some, I want to have all Audio CD, audio book CD and of course language course CD, which have accumulated in the course of the decades, in the car. here my shopping list: Dell Axim X51v (which will be my player in the car) Asus WL-HDD In the WLAN hard disk housing WL-HDD any 2.5-inch IDE hard disk can be installed, on the 802.11b/g Wi-Fi 2.5-wide hard disk: 160GB Seagate ST9160821A Momentus 540.3 160GB ATA (here the data come from) power inverter 150 VA from 12V DC to 230V AC (so I create a 230V network in the car) if someone has a better idea, I’m open to anything.
