enco unit, need some help
i have a 2001 bmw 3 series. i bought an enco unit 2 days ago and it's on the way here right now. i read that i may need an antenna adapter to get radio signal for this unit. all i could find from searching was people buying some OEM adapter cable for $35 - $55 which is ridiculous. my question is, will this aftermarket antenna work? it's only $10 and i can drive down the street and buy one.
