I also have the avant2 and am excited because today my package from Jeff at jandt distributing came with the crossover and 5 channel replacement amp came. My goal for tomorrow is to finish installing the avin backup camera and dash cam as well as wire up the crossover network and amp. My vehicle had factory nav but the previous owner hacked up all the wiring in an attempt to add a sub. she then sold it to me with many electronic issues. One of many issues I should have run from but didn't because I wanted a manual x5. I plan to post photos and stuff from work sunday. I can't say enough nice things about the people with all three of these products.
