Xpresskit Canmax Series CanMax400DEI Docking Combo Bypass and Door Lock/Security Interface

I bought this product for my acura RDX to be used with VIPER 5901. I'm not a mechanic guru so I trusted the website's compatibility wizard and bought canmax400dei thinking it'd be 100% compatible with my car. Everywhere on the website Directed Electronics emphasized its compatibility with my car, except for one single line in the installation manual where it mentions that once the car has been remote started, the remote will not be able to unlock the doors. This is a serious design flaw and Directed Electronics is deliberately deceiving potential buyers on its website. For consumers like me who do not plan to install by ourself, we'd never find the problem until we bought the product.I called Directed support line, and they merely dismissed my problem by saying that "the module mimics what the factory key fob would do - ie. unlock and lock doors + remote start the engine". Their argument is that if my keyfob can't remotes start engine AND unlock doors at the same time, why should canmax400dei be expected to do it. This is very bad business practice and I will certainly be reporting this to BBB in hopes that others will not fall victim to Directed Electronics' malicious practice. I would caution all buyers to check the installation manual to make sure you do not miss any line. If you can't read manuals very well like me, it's best to visit forums and purchase modules that others have tested to be 100% compatible. I HOPE NO OTHER RDX OWNERS WILL HAVE TO GO THROUGH WHAT I HAVE GONE THROUGH.This unit is also not 100% compatible with CRV, Civic, CSX. So buyers beware!UPDATE: I found a better/cheaper alternative for canmax400dei for those with the vehicles I mentioned above. idataLink ADS-AL CA is easy to install and does everything canmax does and more! not to mention it's less than $55 after shipping at other online stores. I strongly recommend it! I have bumped the review from 2 stars down to 1 since canmax really pales in comparison to idatalink.

I'm a professional installer. I own a company that have done over 40,000 remote starters. Over 10,000 I have done myself over the years. I'm very disappointed that Directed discontinued CANMAX400 modules. It simplifies the installation better than many competing products from ADS (iDatalink, Flashlogic), Fortin or even new Directed DBALL. Of course to take a full advantage of it and to get it to work correctly one must be an experienced professional. It's easy to do serious damage to the vehicle if something is not connected correctly, so take your vehicle to a professional. Buy all the parts from the same place where you get the installation done. You won't get a warranty if you bring your own parts. Also installers pay less for product so if you bring your parts expect that it will cost you actually more than if you get everything from the installer. Installer will also use best module for your type of the vehicle. Don't rely on manufacturer's compatibility lists, because you have to be a professional to understand the difference between how different modules work and which one is most suitable for a particular application. If you are professional, CANMAX400 has a memory that holds programs for all applications (like Fortin products) and in case of many (but not all) vehicles offers better functionality than many competitors.

Works perfect on my 2007 Acura MDX and 2004 Acura TL with no issues. Used with Viper and Clifford 2-way remote start systems and I love this module. Huge time saver for wiring and directed communication with the factory system.
