found pre installed remote start

Hello, I purchased a Fortin evo-all. Evo-chrt5 for my 2005 jeep grand cherokee.   When I started ripping the dash apart I found a remote start had been installed before I bought the vehicle. I would replace the remote start with the identical box to makes things easy, but I want to get two way communication and a decent range. The installed bypass is the idatalink ads-al. The remote start installed is auto page rs-603. No remotes Is there a unit made by autopage that I could upgrade to with minimal change in connections? Thanks, Dustin

Oh and ....not planning on using the fortin now.

Hello, I have looked into upgrading to the RS 625. Can anyone help me with the connections I was not able to match up with the 603 below? They are indicated with a "+" next to each one. RS 625 H1, H2, and H6 connectors match identically with RS 603.
