So I did all of the upgrades the Nav, Bluetooth & Sirius Radio.
I want to sell my old stuff that came out of my 2001 750il on ebay.

How much $$ should I expect to get for a MKIII Nav, CPT 8000 phone system and radio?

Any ideas what would be a fair price for each?

Search through completed sales to see what previous sales closed at. Start at $1 and see how high the price gets.
