Patience is not just a virtue, it's a requirement for installing a car stereo control interface. UPDATE: NOT WORKING AGAIN
on August 13, 2017
It was great when it worked.
For a week, it worked fine.
Then, it stopped working.
Then, it worked again, for a few days. Now, it is no longer functioning, conveniently AFTER Amazon's return policy limit. Who knows, maybe it might work again. Or not. Maybe it only works on days not ending in a Y. I don't have time to open up the console and pull it out of the steering column right now. I'm going to make a quick assessment that it's not making a good ground connection with the steering wheel controls, AGAIN, or that little box isn't interfacing with the radio and steering wheel. I'm not investing another dime in this product. What a pain.
Well, it was fun when it lasted.
For the price and hassle of installing this item, I truly expected better. Again, it's a month past the time I can return the unit. Something tells me that Metra wouldn't, couldn't and didn't (and most likely, never will) work out all the possible bugs from this item.
**ORIGINAL PRODUCT REVIEW**
You will need some patience with installing this item. There will be some frustration involved in this task. When you get the interface to accept the new head unit, and all is well, you will be rewarded with having it work the way your factory steering wheel controls did with your original radio. That is the intent, right?
Last weekend (August 5-6) , my husband and I upgraded our 2004 Honda Odyssey EXL factory stereo head unit to a Kenwood DPX702BH model. It made sense to use this control to retain steering wheel controls.
There were problems. The instructions, even the ones we downloaded from Metra's Axxes ASWC are not that clear. After several resets, the unit finally paired with the Kenwood receiver and the steering wheel control va the correct sequence.
Another problem came to light, but was not necessarily the fault of this unit. When using the steering wheel control, the unit would operate correctly only IF the steering wheel was straight- i.e. moving volume up and down, changing stations, i.e. what you want the the control to do. IF the steering wheel was turned to the side, any side, when you used the control, the volume would go up erratically, on both of the up or down controls, and radio stations would fast scan, or not change at all. Testing it with a cd player had the volume go loud in the same way that the radio acted with the control, with the inability to change tracks. I thought the Axxess control was defective. It really looked like this was the case. Again, I can understand WHY someone will claim the unit doesn't work.
The root of the problem turned out to be a poor ground connection with the steering wheel and the control unit. The problem did not exist with the old stereo. The problem came to light with the new Axxess cable control, spliced into the connection to the original steering wheel cable assembly.
We were able to diagnose the problem from information on the Odyclub Forum website regarding the control interface connection, and problems stemming from service bulletin repair work 03-022 on the steering wheel. The copper contact plate inside the steering wheel was not dimpled (notched) correctly. The Axxess unit was configured to read the copper plate as if the service work was handled correctly. We set the small dimples in the plate correctly, then reset the steering wheel controls (with the battery disconnected, of course.). After all of this, the unit seems to be working correctly.
Even if you plan to buy this item and have someone else install the control, please make sure they test it in different positions to check that it works properly when the wheel is moved. Check your ground connections on the steering wheel. This is not a fast job. Once again, patience is a necessary requirement with this installation procedure.
