I have a 2009 ultra classic that I installed a jensen hd1bt with Rockford fosgate punch 300x4 amp.
When I turn radio on it triggers alarm code bus and the key and another symbol lights up on dash.
Has anyone else had this issue?? Does it have to do with alarm system?

Update...so what is happening is whenever I turn my radio/amp on my speedo and tach stop working. If I turn radio /amp off speedo and tach start working...
If anyone can give me some advise as where to start that would be great
