Hi All,
I bought the above Alphard 18 months ago. One of the changes we made was to replace the Head unit with an Android unit. Last summer we went to the Iberian peninsula for 7 weeks touring with no problems.
A few weeks later just as we were setting off to Anglesey this time the van stalled. We eventually got it to our local garage who were too busy to look at it. So we decided to get it transported to a garage in Worcester that was recommended by the importer we bought the van from. They diagnosed that 2-3 cells of the hybrid battery were faulty. These were replaced. Then we were told that the original Head unit needed to be re-fitted to test the battery. We didn’t have it. We bought another from eBay but then we were told that the wiring had been bodged so much that it couldn’t be done easily. We were then told that the Head unit was used to re-charge the battery and the Android unit thus was not compatible. It’s not yet fixed as they are now looking for a different Head unit with different connections on the rear.
Can anyone suggest a way forward? Can anyone confirm that Head unit is indeed used to re-charge the HV battery.
