Baffled By Aftermarket Headunit!

[BAC]

hi there. ive got an alpine headunit which id like to fit to the lexus. bought a fascia and that fits perfectly. so went down to Halfords and thought id be a clever **** and buy the toyota adaptor lead, got home tried to fit it, fitted the headunit but wouldnt fit the car. got onto eBay and found one of these: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?Vie...em=150333199627 thought PERFECT, turned up today, exactly the same plugs as the one from Halfords. on reading the eBay listing it says it fits non amplified is200's only. im baffled as i didnt think mine had an amp as the sound quality is rather poor!! would this all suggest different? and if so what lead do i need now??

Yes, what you bought on eBay is a standard Toyota adapter which will work for IS200 models without the additional amp.

Have you got the extra amp ? It's hidden behind the glovebox on the left side of the car. If you have an SE or Sport model then you'll have it. In which case you'll need an amp bypass lead like this one, which as the name suggests, bypasses the amp and connects the new head unit to the speakers etc.

If you have OEM satnav then you will also need an extra box of tricks to make your satnav work with the aftermarket head unit. If you don't have OEM satnav then you don't need that (but still need the amp bypass lead).

Here is a walkthrough and pics about attaching the amp bypass lead, which also shows where the amp is in the first place. You don't need to remove the amp afterwards, but it won't be doing anything any more.

While on eBay the other day I noticed now that there is finally an Autoleads amp bypass cable, and bizarrely it's cheaper than all the others!

It's about time they made it, weird how it's only available 4 years after they ended production
