This may be a redundant question but the U7135 works with the 03 hemi right? Their site says 2005-2010 or something along those lines.. I know the inTune works with the 03 which is just an upgraded U7135. Some sites have the 03 listed as a vehicle supported and some don't. Found one on a website for $150 so I was thinking I should pick it up.. any help would be appreciated.
