Massey 7726 radio problems

[Scu6499]

I’ve been having issues with the existing radio in my 7726, and wanted to change I usually do this in all my tractors with little bother, but for some reason I can’t get it to work in the Massey, I cannot save any memory settings in the new radio as the automatic isolator cuts all power to the radio so doesn’t keep the memory line live it also cuts the earth aswell, have tried running power straight from battery to keep it live but this caused the isolator to no longer isolate other stuff. Has anyone experienced this and found a way round it or do I need to buy a genuine radio from my Massey dealer?
Thanks in advance

Back feeding through the neutral. Run a seperate neutral as well.

It wont work running a separate neutral you have to buy a radio with a built in battery to keep the memory. You can get them from halfords just have to do a bit of searching for the right one.

Surely if you run a separate ignition feed off the back of the key and a separate neutral back to the battery the radio is completely isolated from everything else. As far as I am aware that's how we done it.

Like Masseymad say buy one with built in battery, it the best way to fix it. You can buy one cheap online just search.

We tried running a live and a neutral straight of the battery on ours and it was turning the isolater back on if it can be done I'd love to know cos I've got two radios that have to be tuned everytime you get in the cab

I'll have a look and get back to you.

It can't be done. Any extra wiring will affect the battery isolator.
As above - you need a head unit with back up memory.

I have a Kenwood in a 7720 . I have to switch it on and it starts up on any random dab station , I have the local station stored to 1 and pressing it will come up as no signal . If I then press for fm with the local station it will hold the station for maybe 10seconds then switch itself back to dab for the local station . It seems to just want to play dab rather than hold fm signal.

I've played with the settings but it always seems to revert back to above so blamed the auto isolator
