I need to set the tuning on my Sony car stereo from Japanese to US tuning

Resetting/Hacking Sony Car Stereos from Japanese Tuning to US...service manuals?

Hi there...

I need to set the tuning on my Sony car stereo from Japanese to US tuning.

I was wondering if someone has any idea if ANY of the Sony "WX" series of double-din car stereos (japanese or usa models) can be "hacked" so that their tuners can be changed from japanese fm tuning to us/uk or world tuning and vice-versa???

I recently purchased a Sony WX-C88REC double-din cd/md recorder from eBay. This is a japanese market deck and is factory set for japanese fm tuning. However, the design and physical layout of this deck is very similar to other US models (such as the WX-4500X and the WX- C5000, as well as the WX-C55 which looks nearly identical). I'm nearly convinced that there MUST be some way to hack the japanese models so that their tuners can be "switched" to us or world frequency range tuning. I find it difficult to believe that Sony would design two distinct different tuner hardware modules for japanese and american versions. Problem is, I have no clue HOW to "hack" this feature. I don't have a service manual for ANY "WX" series stereos, but I'm thinking that it may possibly be an option in a service manual for ANY of the "WX" decks. Again, I find it difficult to believe that this isn't "set-able" some sort of way.

Does anyone out there have an idea? Does anyone out there have ANY service manual for ANY "WX" series Sony stereo? Or, for that matter, does anyone have a service manual for ANY Sony car stereo that addresses in ANY way setting the tuner for different tuning freqency bandwidth?

I realize there are adapters available to transpose the FM frequencies. I've used them before, always with poor results (stations usually overlap and are weak). I mainly record off the radio with my MDX-C800REC's in my other cars, but always thought it would be cool to be able to dub cd's quickly in-dash digitally without having to mess with a cd changer. But, radio recording is my primary concern...and the adapters don't provide the quality I want for recording.

PLEASE help ANYBODY if you can steer me in the right direction or help in ANY way. If anyone has ANY Sony service manuals for ANY stereo, please let me know...perhaps if setting the tuner IS an option, maybe it is a standard procedure to set ANY Sony stereo's tuning in a similar fashion.

Thank you VERY much! Jeff

This is not a design issue. Try news:sci.electronics.repair

You need a frequency converter...

Most of the radios I have played with for different markets have a few diodes or 0 ohm resistors that need to be changed to make them think they are one or the other. A service manual for one or the other or both can help you find that. But that only gets the MPU to think it is one or the other. You then have to re-turn some center VFO voltage or some such. Not always trivial. My guess is it won't be worth the aggravation.
