I have a X5 with an Ambicom CF wifi card, Linksys HUB in the house and Netgear usb wifi dongle in the car. My pda has no problems connecting to any of them. Iv also tried the adhoc in the car and that works fine too. I tested out Netremote and its pretty cool, but a tad bit too much fiddleing around for my likeing. I pretty much gave up the idea of using the PDA as a remote control in the car, even though i had it all setup and working. I was able to control the pc, move the mouse, control winamp etc, and also control my Sony HU and XM radio with IR. Its just easier for me to use the touchscreen, and in the end seemed like a lot of setup work for nothing. But.... if your just trying to control your music and nothing else from your PDA, Vinyl is pretty damn cool and works good.
