So I've still got we old audio equipment that I've been using for years which includes the alpine w200 and pxa-h701. The w200 CD mechanism quit working s while back and now the touchscreen is giving me trouble. It's strange because if I use my finger for some of the functions it won't work but I happened to have a row of magnets that I can touch it with and it works most of the time. Will any of the newer head units control the old pxa-h701? It still works great so I hate to buy a new processor and head unit when the processor is still good.
