I'm sorry but I have to disagree about the sound quality. A self made cable and cheap 3.5mm converter will only barely match the hpm70, if not worse. Yet the MMC-60 is way better quality audio transfer than the hpm70, so I can't see your solution offering the same audio quality as the mmc-60.
By all means it may be an alternative for someone trying to save a buck, but it's not a better alternative technically speaking. And I'd be surprised if you can build a cable cheaper than buying one. Here in Australia, You can get such 3.5mm to rca cables for $5, where as a length of cable, two rca jacks and a 3.5mm jack will cost atleast $8 (more if you use gold plated connectors).
And at $23 the mmc-60 is about twice the cost of the adapter and cable you suggest, for substantially better audio quality. I personally think the extra cost is worth it. And even if I went with the fastport to 3.5mm adapter I wouldn't bother making my own cable (which will cost me more) I'd just buy one off the shelf. Believe me I like modding shit like the best of them, but why bother with something as trivial as a 3.5mm to rca adapter lead? I'd rather spend the time doing more mods to my Car-100 
I'm not arguing that your suggestion won't work; it will. And I'm not arguing that it isn't a cheaper alternative; it is. However, it simply won't offer the same audio quality as the mmc-60.
I'd strongly advise anyone who can afford to spend the extra to make their own cable, actually put that money towards the mmc-60 rather than chance wasting it by building a cable that offers too high resistance because the soldering isn't 100% (audio connections are very demanding and must be perfect or signal loss will result).
Believe me audio soldering is critical. Building your own audio cables is not for the beginner. Not if you want any sort of reasonable audio quality.

I was able to use my phone even with the cable attached. Though I'm not having the conversation through the car speakers, I was just holding the phone as I would regularly. |

okay, that's good news. I guess that's why it doesn't change to handsfree profile - because then the mike would be disabled as it is when a handsfree is attached (to use the mike on the handsfree)
Since it doesn't switch to handsfree, when a call comes in audio functions revert back to the phone, not the cable.

i actually made my own 3.5mm to rca cable, so far i haven't experience any problem regarding sound quality. soldering doesn't require any skills anyway  my 11-year old nephew already knew how to use the soldering iron.
what i am trying to point out that there is always a good alternative solution in every problem that one might encounter. like for instance, if you have already an adapter like the hpm-70 (that has a built-in mic), you can either BUY (the ready made one) or MAKE (if you wish) a 3.5mm to rca cable. that would save you a buck rather than buying an mmc-60!
so if you're a beginner and don't know how to solder, then, buy only the ready made 3.5mm to rca cable instead of buying a new mmc-60 then connect it to your hpm-70 adapter. That's it.
that's the point, and that is why it is being called an ALTERNATIVE SOLUTION as what @rockygali is asking for.

fair nuff
Still, here in Australia, as I said, it's more expensive to make your own, unless you already have spare components (you still had to pay for 'em somewhere along the line).
And about the soldering, I disagree. Some people have an apptitude for it, but most beginner solderers make an ungodly mess. Audio cables with RCA plugs are more demanding than steel 3.5mm plugs with regard to signal attenuation. You need a good strong connection, otherwise the audio quality will be no better than a 3.5mm connection. There is a reason RCA plugs are used in stereo equipment; it provides much better signal transfer than 3.5mm plugs.
Obviously you have done a good job on yours. But until you test against an mmc-60 you can't say your cable and adapter give as good a connection as a single mmc-60 lead. As I said, the difference in mmc-60 and the hpm70 is marked - the mmc-60 is quite a bit better in audio quality. I can tell, and I'm no audio expert.
To make you own mmc-60 (to give the same audio quality as the real thing), you would need to use gold plated rca plugs, and to avoid the break where the 3.5mm adapter plugs into the cable, you would require a fastport connector as well. (Breaks introduce attentuation as well).
So your cable works fine on an adapter or even a hpm-70, but it still doesn't rival the audio quality possible with a true mmc-60. Another disadvantage with the home made cable, it doesn't have molded rubber plugs, so the cable has to be treated with care so as not to stress the connections. A manufacturer cable is more durable.
I'm not dissing your effort or information, it is certainly an option. I'm only pointing out that audio quality is better with a true mmc-60, and that in some cases it may actually be more expensive to make you own cable.
