While this is true (about Cardaq M with Mega Can) the cost is about the same as having a micropod2. You need to have a Witech script and have the CardaqM w/MegaCan. So to save the $1800 for a pod isn't really worth it that much for the hassle you can save. Also, the new Cardaq 3 should meet the requirements and be an approved device soon for Chrysler R2R software soon.   Nissan is going to change their R2R software wither this month or next. It should do All 1996+ with the consult software including programming which it currently doesn't offer. I'm hopping this works better than Nissan track record of J2534 software. The best part is no CF19 required or Consult 3+ interface. This is one I would gamble on because the OEM tool is crazy money due to the fact it comes with a CF19

On some you can trick it with Tech 2 by choosing a earlier year . forgot what years but I have done it with CTS 

While I agree with that it does get messy when trying to figure out some of the uplevel stuff. I've had all kinds of weird stuff happen when trying to do things like enable a backup camera or add nav.  I have not done it in several years. . . basically since the ones that required tis2web started showing up. When only the Tech2 was required it was relatively easy. Once the laptop and cellular data and subscriptions come into play I priced it out of what anyone wants to pay. And given the success rate was on the low-rent side of "iffy", I pretty much quit. If the radio they show up with isn't compatible or is broken, etc. the situation devolves into  "well can't you try programming it harder?"  That's not low hanging fruit. . . them's rotten apples way up the tree. 

On most models, under entertainment , radio, relearn vin. Some of the older models are just straight under radio some under body electrical...   Videos I could find on a few models all seemed to just do it instantly. They were mostly older vehicles tho.
