I have given this a lot of thought. All the videos I have seen show the buttons on the unit (not the screen) as functional. As I understand it, yours are not. It seems that locked units do offer some responses, whereas yours doesn't ! Does the unit allow you to tyre a password, albeit incorrect. If so, that would suggest the unit is not faulty (another concern of mine) just performing its anti theft function. What did the dealer say when you bought the vehicle ? Did he explain the HDD was not functional ? Is the dealer able to replace it with a functioning unit ? I assume you have explored that line of enquiry. I sent him a photo of your unit. I'll get in touch with him again.

Hi Doug, Welcome to the Forum.

Could it be anything else? Where I live we have had a dramatic change in the weather !

Not good news. Have you watched the Cuttothechase video. It may reassure you somewhat ? Did you fill the tank? If not, I suppose you can 'dilute' the E10 by filling up with E5. I expect in the next few weeks we will get lots of feedback from users of E10.

Hi Mark, Since earlier this year, I believe, fitting a pop top will cause the vehicle to need to be reclassified as a motor home. What difference this makes, I don't know, but just wanted to make you aware so you can make further enquiries if you choose. Hopefully, I'm not wrong on this, but if so, I'm sure I'll be corrected quite quickly.

Hello Jenny, Possibly some good news. I have been searching virtually all afternoon for an English manual for your NHZN-W57, without success. However, I have also contacted someone in Bangadesh requesting if he can still overcome locked units. He has now responded confirming he can. He has requested $20 usd and some photos of the unit. I realise this could be a scam, but I don't think so. I have approached him, not vice versa. If it were me, depending on how the payment is made, I would risk it. I can't see any risk in sending him a photo, or two. I wrote to him as a Moderator of this Forum and he is offering the service for $10 usd if I include a link to him. I cannot see why I shouldn't, furthermore, if you were not successful I might publish that also on the Forum. Is it OK for me to contact him on your behalf, or would you prefer to do that, or would you prefer to take no action at all. If you wish to proceed, I'll contact you privately.

I am not quite sure what you are asking. It is cooler here than in Honkers, but does not get cold enough that heated seats are essential. You can purchase aftermarket seat warmers, although I never have.

Cuttothechase on youtube

DON'T disconnect your battery. I am just reading this may be what created the problem.

Hi Jenny, I have been looking at youtube and there are several videos that purport to unlock your particular HDD head unit. Some involve a small payment. Unfortunately, none of them (so far) has a procedure that starts with the screen you have. Actually one does, but as soon as the buttons are touched it busts into life and he shows how to unlock it. Please confirm, whatever you do, the screen is stuck in the keyboard ? Have you tried disconnecting your battery. Please note if you do you will probably need to reset windows (a the sun roof if you have one). As it seems totally unresponsive I wonder if it is faulty, rather than not knowing how to unlock it. I'll keep looking for a solution.

Sorry I misled you. I did not realise there was another HDD unit; other than the one I have. Somewhere, I found a video of a gut unlocking a head unit. Now I know which unit you have, I'll have another look.

Sorry, they do suitable Rims for a specific tyre too !

If you go to oponeo.co.uk You can use their Tyres suitable for a xxJ rim. Lots of choice. Be aware of the clearance changes, as noted before. Those that colin2 should be OK for winter use ! Only £200 !

Charlie, Please remind me which 2008 model you have ? What is the model number ? MH ? I think you have 6.5J wheels; I am just trying to check. The wheels will be stamped (on the inside !).

Hi Charlie, Do you have standard wheels and tyres fitted now ? What size tyres do you have , which you hope to fit to both set of wheels ? Did you look at the wheels for sale in this Forum (Sales section) ? When you buy more tyres will they be winter tyres ?

Oh dear, oh dear ! Try Malaysia too. Alphards were quite popular there. Jenny, you don't have the HDD unit. Either you, or I, or both, are becoming confused ! In summary, we think your head unit is password locked ! Did you speak, or contact, those persons who claim to be able to unlock these for free, or for a small fee ? There is a chap on ebay, who I have read good reports about, who is able to 'tinker' with Alphard head units. He is located in Birmingham Search ebay for beanbean280r. Hopefully he will be able to help you. (He is not cheap). There are many Forum members who have upgraded their head units in various ways. So, don't lose heart' the solution is in here somewhere ! I still have my original HDD unit, so cannot recommend specifically which way to go.

I don't disagree that E5 is the preferred fuel. Nor do I disagree with Picasso. However, what is interesting is that Cuttothechase (on youtube) has put up a video which purports to show the ECU adjusting the engine settings when fed E5 / E10 fuels. I can find no reason to question his findings ! If I understand his findings correctly, he finds the ECU adjusts to the fuel the engine is fed. (He does not, as I remember, speculate on long term effects of either fuel). What is of most interest to me, in the above case that Picasso cites, is what is the corrective action that the vehicles need. (Hopefully, not the O2 sensors). if you wish for further reading,, I have already provided two American studies on the use of Ethanol fuels. Should you be interested please search my profile. They may, or may not, help you consider the risk of using higher Ethanol fuels. Respectfully,

Sorry Jenny, I forgot which one you had. Trip to Halfords this week ? Good Luck and let us all know how you get on; what unit you select, etc.

There is another website, which I will need to find that describes what wheel tyre combinations are OK, and which are not. I'll try and find it for you. It is something that explains the J wheel sizes. Are you intending to have two sets of tyres on two sets of wheels; or one set of tyres for two sets of wheels ?

Search for colin2, or Colin2.

Charlie, One mm difference in offset is OK. It won't make any difference. Go to the Willtheyfit.com website. Put in 205 65 16 on the left hand side and your new wheel size on the right. If you scroll down it will tell you whether you will lower, or heighten, the van Whether your wheels will move inwards, outwards, or both. I'll try and find the ad. Will come back to you.

If you are changing away from standard size OEM wheels go to Willtheyfit.com and play with their wheel and tyre size model.

Hi again Charlie, Check out my previous posts to you regarding wheel sizes and tyre sizes. MZG are 205 65 16 95H all round Bolt pattern is 5 stud on PCD is 114.3 You need a 6.5JJ rim with an offset of 39mm There are some wheels and tyres on here for ONLY £200. Run flat tyres may require a different rim. There are tools on the internet to ensure tyre size and wheel size are compatible if you wander away from the OEM sizes above. I don't know what the centre size is but Driftworks will have spigot rings in different sizes

Hi Charlie, Did you bid above the reserve ? If you won, then I guess you did. If you didn't, that's the way it works. I buy a lot on ebay. REPORT the Seller. They can check you 'purchase' history with this buyer and item; and then take action.

Hi Sparkie, Welcome to Alphard ownership and this Forum. Search this Forum for E5 / E10; you'll find plenty to read and help you decide.
