Report Shaker 500 replacement help please in Head Units-Processors and Eq's Posted April 9, 2021 have been searching all over the internet and cant seem to find any relevant current suggestions on a current make and model head unit to replace my Shaker 500 unit in my 08 Mustang. I want to keep the door subs and will need hands free calling for a I-Phone. Ability to query Siri (directions ect) along with integration would be nice but no GPS. Great FM reception and sound. Would like to stay under 500.00 Single or double Din not a issue. Ease of use while driving. Thanks all for your thoughts and time.
