Just wanted to let you know about a couple of web sites.
If you are looking for car LCD screens and in-vehicle entertainment components check out www.carlcds.com , there is a wide range of high quality products at good prices. Check out some of the in-dash options for your BMW.
Also, if you are looking for the ultimate in mobile multimedia check out www.gnetcanada.com we sell complete in-vehicle computer systems that play MP3s, digital video, DVD's and also support GPS tracking and wireless internet. Check out the "Customers Installations" section for an overview of a BMW M3 install.
P.S. I use this board daily for BMW related topics but every so often (once every 3 weeks) I post these messages, please donít take it as Spam, I am just trying to promote this company as much as possible.
