Hi mate, get an icom 440 or the other (uniden and gme) that have the remote mount. There's plenty of room in/around the dash area in the FJ. I got the Icom 440 with remote mic and fitted the head unit under the centre console where the motion sensor for the stability control is, easy fit and the Icom has speaker and mic in the handset. If your 2013 doesn't have the overhead controls then I know there is a overhead aftermarket console available but I am told they are very expensive.
