Query: Works sometimes, but not worth it

I bought this and installed it on my 2001 BM& 740il...but it didn't work. Dice service was very good, they sent me a replacement even though I did not buy from them, Got it working finally.... but every couple weeks it stops working and I have to work to get the unit to see my ipod. This, combined with "ok" but not great sound quality (this may be because I had a digital equalizer that we had to change to analog (another Dice product) made this a lot of work... would have been easier to have burned cd's and changed them occasionally...... just my two cents.
