I'm just guessing but maybe year or manufacture? 07/2003 - 03/2005 04/2005 - 11/2011 12/2011 - 20/2013 11/2013 until now

What version of Techstream are you using? I found that only 18 automatically detected Alphard. You also have to make sure your region is set to Japan.

How is a mongoose connector different to a J2534 MVCI cable? This is the one I have https://www.ebay.co.uk/itm/124808047632 I can't seem to find a mongoose cable anywhere.

This is exactly the same. I'm pretty sure its not the cable as have tried different ones with no luck. The fact that the Bluetooth OBD2 can connect but can't edit anything suggests is something to do with the car rather than the cable/dongle/laptop etc. I saw some posts about the ECU not having enough power but my fuses appear to be ok. Please let me know what happens when the specialist has a look at it.

Did you have any luck with this? I have just got an Alphard and these beeps are driving me crazy too.

Doh! Thanks. Ok, so changed it to Japan and that has fixed one issue. I now have options in the customize settings menu. But now a new problem - I can't edit any of them. The customize parameters box is empty (attached). This is for everything in the customize menu. I thought I had read on other parts of this forum that people manage to change the beeps or at least make them a single beep?

Hi, I have just bought a 2005 Alphard and had it converted into a camper so new to all things Alphard. I love it but the door beeps, tailgate beeps, reversing beeps...it's too much. So I have searched and searched on these forums and the general consensus is to get a bluetooth OBD dongle and app or Techstream. I have bought (and returned) several Bluetooth OBD2 devices. Non worked. Some would connect but non would let me change any settings. So I am now going the Techstream route. I have a MCVI cable and various versions of Techstream. All the older versions I have (v12, v13, v15, v16) don't have Alphard in the list of Toyota models. The version that came withe cable (v18) automitically detects the vehicle but when I go into customize settings the screen is empty (it connects to the vehicle ok as I can see various bits of data) but I just can't change anything in the customize screen. It's empty (screenshot attached). Anyone got any thoughts? Am I missing something? Have you seen this before? I have used a couple of different drivers and made sure I have changed the VIM select. Like I said, V18 seems to connect to the vehicle, just missing customize options. Earlier versions won't let me even choose Alphard.
