The GPS system in my 2000 740il is out of wack always saying that I am out of the map limits. The dealer checked it out and told me I needed to replace the antenna and it costs $450.00 for a new antenna. I found an antenna on ebay for $20.00 does any one have information on how to replace the antenna? I would like to try and do it myself to save some money.
Thank you very much,
