The one small advantage overnlater PCM systems is that because it has a tape deck, it is quite simple to connect up your phone or iPod etc using a tape to mini phono jack converter things that you can buy anywhere - old technology yes, but it is simple and cheap!

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

My sat nav didn't work when I bought the car but got the CD drive repaired and got 2011 maps for it.

POST 1 / ORIGINAL POSTEROriginal post

This is what's in the car already. It has the Bose system. Does my car use the MOST fibre optical system or the analogue system? Are the speakers any good ? Would like a more modern headunit, with bluetooth and decent navigation. I already have an Alpine ILX700 which does this and integrates with my phone. I have a decent amp I had in my other car that I could use, a Hertz HDP4. Can I use that ? What's involved ? Cheers

POST 2Original post

I think that's PCM1 as it has a cassette deck. Anything is possible, upgrade-wise. The Bose subs are very low impedance so can be tricky to drive. You might have to google the PCM1 to find out if its MOST (I don't think it is though) If you're going to install a new amp, you'll be routing RCA/phono cables from your new head unit anyway.. The Bose speakers are ok.. But you get get much better if you spend money. Law of diminishing returns though as the cabin isn't well insulated...

POST 3Original post

PCM 1 and no MOST / Fibre optic cables .... its all hard wired .

I Have this PCM1 system. The one small advantage overnlater PCM systems is that because it has a tape deck, it is quite simple to connect up your phone or iPod etc using a tape to mini phono jack converter things that you can buy anywhere - old technology yes, but it is simple and cheap! If you are looking to connect a phone using bluetooth - consider https://www.elektronikidee.com/index.php?option=com_content&view=article&id=20&Itemid=109&lang=de Can't find the button for the English language version of the website on my phone but they do have one My sat nav didn't work when I bought the car but got the CD drive repaired and got 2011 maps for it. Don't use the nav much, but it bothered me that it wasn't working. I used the company in the link above and they were very helpful When I have refreshed my suspension and done everything else I need to do to restore the original feel back into my C4S, if I have any money left over, I'll consider the head unit replacement! Until then - the PCM1 is my friend!
