I have a Sirius Starmate 5 dash unit and I love the large display with info and buttons to switch stations easily. I was considering getting the Sirius kit for my avic-f700bt but have read mostly bad reviews on the interface. I read that you only see one line of info displayed and that overall it's pretty poor. I wanted to get some opinions on whether or not I should keep my dash unit, better info and ease of switching channels, vs. HU, cleaner install but worse interface. Thanks in advance!!
