Vias kit came with the vcais interface and a sirius connect tuner with a small antenna with 10 foot cabel . I mounted the antenna next to the passenegers windshield pillar. I ran the wire and pressed it into the crevice between the pillar and the dash. I then ran wire down underglove box [ removed lower garnish panel very easy just clips out ] then tucked wire under lip of center console and fed it into where i had velcro both small control boxs in the hollow area of the center console , I get good reception but if i go under a lot of shaded trees i do occasional loose the signal some times . I paid 300.00 frrm integration solutions ebay vendor. The new vias unit firm ware 4.38 fixed a lot of bugs people were experiencing, I have been enjoying ine for 3 weeks with no issues . The kit form integration solutions gives you evrything you need to install . The oem harness they make that allows you just plug and play and makes install easy.
