Gdl 50 vs 50r

Can anyone weigh in on the advantages of going with a gdl 50r over the gdl 50? I have a G3X in my -8 and want the ads-b in for obvious reason plus to use as a backup ahrs as well as run a rear iPad for the passenger. It appears that the gdl 50 would be a much easier and more versatile option than the 50r. If I use a designated cig lighter to power it I shouldn?t ever have power issues, I could potentially remote mount it somewhere and run a remote antenna, and I also have the versatility of removing it and taking it to another plane if needed. Is there some huge benefit to the 50r that I?m missing???

Does the remote version have a battery? The portable offers support if the ship's power should have to be shut down. Not sure about the remote version.

Yea Marty, it does have a battery. Its supposed to last 8 hours. thats a good point... It would be a level of redundancy if you lose electrical
